Spontaneous Intracranial Hypotension (SIH) ne Post-Dural Puncture CSF Leak: Obulumi bw’omutwe obuyitibwa Orthostatic Headache Relieved Flat, Subdural Hygroma, Brain Sag, ne Epidural Blood Patch¶

Spontaneous Intracranial Hypotension (SIH) ne Iatrogenic Post-Dural Puncture Headache (PDPH) mbeera ez’amangu ez’okukendeeza ku bunene bw’amazzi g’omu bwongo (CSF) ezireetebwa okumenya mu spinal dura mater ekisobozesa CSF okutoloka okuva mu kifo kya subarachnoid okuyingira mu nkola ya epidural oba paraspinal venous system eyeetoolodde amangu okusinga ekitundu ekiyitibwa choroid plexus kisobola okukijjuza. Ekikulu, wadde nga ekigambo "spontaneous," ebitundu ebisukka mu 98 ku buli 100 eby'emisango gya Spontaneous Intracranial Hypotension biva ku kukulukuta kwa CSF y'omugongo mu mugongo gw'ekifuba, ogw'omumwa gwa nnabaana, oba ogw'omugongo, SSI kukulukuta kwa CSF okuva mu kiwanga ky'omutwe (okukulukuta kw'ekiwanga-ku musingi kuleeta amazzi mu nnyindo oba okuwunya kw'amatu n'... meningitis, naye kumpi tereetera kulumwa mutwe nga orthostatic brain-sag kubanga puleesa ya CSF y’omutwe eba zero oba negative nga yeegolodde). Enkola y’omugongo ey’omulembe (Dynamic CT Myelography ne Digital Subtraction Myelography) egabanyaamu okukulukuta kwa CSF mu mugongo mu bika bisatu eby’enjawulo eby’omubiri: Ekika 1: Ventral Dural Tears ekifumitiddwa ekirungo ekiyitibwa calcified thoracic intervertebral disc osteophyte microspur (\(30\%\) okutuuka ku \(40\%\)); Ekika 2: Lateral Meningeal Diverticula / Nerve Root Sleeve Tears (ebitera okukwatagana n’obuzibu bw’ebitundu ebiyunga eby’obusika nga Marfan syndrome, Ehlers-Danlos syndrome, oba autosomal dominant polycystic kidney disease); ne Ekika 3: CSF-Venous Fistulas (CVFs), akakwate akatali katuufu aka microscopic wakati w’omukono gw’ekikolo ky’obusimu bw’omugongo ogw’omu kifuba n’omusuwa ogw’omugongo oguliraanyewo ogusika CSF butereevu mu musaayi nga tegulese ttonsi limu ly’amazzi mu kifo ky’omugongo ku MRI eya bulijjo. Obunene bwa CSF bwe bukendeera, omutto gw’amazzi agabuuka oguwanirira obwongo bw’omuntu obwa \(1,400\text{-gram}\) gubula buli mulwadde lw’atuula oba lw’ayimirira: obwongo buseeyeeya wansi mu foramen magnum, ne bugolola obusimu bw’omutwe obuwulira obulumi (CN V, IX, X) era ne buziba emisuwa egy’omu maaso, ate nga Monro-Kellie enjigiriza ewaliriza okuzibikira kw’emisuwa egy’okusasula mu bitundu by’omubiri ebiyitibwa pachymeninges, pituitary gland, n’ekifo ekiri wansi w’omumwa gwa nnabaana. Kino kireeta pathognomonic "Orthostatic Headache": omutwe ogw'amaanyi ogw'ensingo ogw'enjuyi zombi ogw'omutwe, ogw'omu maaso, oba "okuwanirira ekkooti" (okuwerekerwako okuwulira okuzibye "wansi w'amazzi", okuwunya, okuziyira, oba okulaba emirundi ebiri egy'okwebungulula okuva mu kusika kwa CN VI) okukwata omuliro mu ddakiika ntono ng'otudde oba ng'oyimiridde ne gubula oba okulongoosa ennyo mu 15 okutuuka ku ddakiika 30 ez’okugalamira ddala nga zipapajjo (\(0\text{ degrees}\) supine). Singa tebajjanjabwa oba nga tebazuuliddwa bubi, okugwa kw’obwongo okw’amaanyi okudda wansi diencephalic/tonsillar brain sag, tentorial-edge bridging vein tears ekivaako bilateral Subdural Hygromas oba Subdural Hematomas, oba Cerebral Venous Sinus Thrombosis (CVST) bisobola okugenda mu maaso okutuuka ku kuzirika, coma, n’okufa kw’ekikolo ky’obwongo. Singa omuntu yenna afuna obulumi obw’amaanyi obw’omutwe obuyitibwa orthostatic headache nga bwegatta n’otulo, okutabulwa, amaaso agatali ga kigero, obunafu bw’ekifo, oba omutwe ogulekera awo okutereera ng’agalamidde, kuba essimu y’omu kitundu kyo ennamba z’amangu amangu ago. Era weetegereze ebiragiro bya baganda baffe ku... oluvannyuma lw’okuboola omugongo epidural wet-tap headache vs. spinal hematoma, . okuvaamu omusaayi mu bitundu by’omubiri (subarachnoid hemorrhage), okulumwa omutwe mu kubwatuka, n’okukutuka kw’emisuwa gy’obwongo, era obuvune ku mutwe n’okukonziba bbendera emmyufu.

Ekintu kyo eky’amangu eky’okukulembeza kwe okuteeka omulwadde mu bujjuvu ddala (\(0\text{ degrees}\) supine) oba mu Trendelenburg (\(-5\text{ okutuuka ku }-10\text{ degrees}\) omutwe wansi singa ali mu comatose okuva ku severe brain sag), TOkola blind burr-hole evacuation oba craniotomy ku bilateral subdural hygromas/hematomas caused by SIH nga tonnasiba kukulukuta kwa CSF kw’omugongo (okufulumya amazzi mu kukuŋŋaanyizibwa kw’omugongo ng’okukulukuta kw’omugongo kukyasika CSF wansi kusika ekikolo ky’obwongo ekiseeyeeya butereevu okuyita mu tentorial incisura ne kireeta okuwunya okufa wansi), ssaako Intravenous Hydration (\(0.9\%\) Normal Saline) + Intravenous or Oral Caffeine Sodium Benzoate (\(500\text{ mg}\) IV mu ssaawa 1 oba \(200\text{ okutuuka ku }300\text{ mg}\) PO) oba Bilateral Greater Occipital Nerve / Transnasal Sphenopalatine Ganglion (SPG) Block okumala amangu obubonero, funa Brain MRI ne Gadolinium Contrast (nga weetegereza 6-point Bern SIH Score / "SEEPS" mnemonic) nga kwogasse n'omugongo gwonna Heavily T2-Weighted Fat-Suppressed MR Myelography, era n'okukola Autologous Epidural Blood Patching (EBP, \(20\text{ okutuuka ku }40\text{ mL}\) ey'omusaayi ogw'emisuwa ogutaliimu buwuka ogufuyiddwa mu kifo ky'epidural), CT-Guided Fibrin Glue Patching, Okulongoosa mu misuwa Onyx Embolization of a CSF-Venous Fistula, oba Okulongoosa mu misuwa emitono Okuddaabiriza Dural.

Kino kikole kati¶

1. Teeka omulwadde nga yeefudde ddala ku mugongo (\(0\text{ degrees}\) ng’agalamidde nga tolina mutto) amangu ago. Okugalamira nga muwanvu kimalawo hydrostatic gravitational siphon eggya CSF okuva mu spinal dural defect era kiwummuza okusika okudda waggulu ku sagging meninges n’obusimu bw’omutwe mu ddakiika 15 ku 30. Singa omulwadde alina SIH emanyiddwa oba eteeberezebwa agenda akendeera oba agenda mu kkoma (diencephalic brain-sag coma), ekitanda kiteeke mu mbeera ya Trendelenburg (\(-5\text{ okutuuka ku }-10\text{ degrees}\) head-down) era oyite ow’omu kitundu kyo ennamba z’amangu (911 mu Amerika/Canada, 999 mu Bungereza, 112 mu EU, 000 mu Australia).
2. Manya omutwe ogulumwa omutwe bwe gufiirwa enkola yaago ey’okusiba (Red Flag for Subdural Hematoma oba Cerebral Venous Sinus Thrombosis). Nga bukyali mu SIH oba PDPH, omutwe gubula nga gugalamidde. Singa obulumi bw’omutwe bukyuka mangu ne bufuuka okulumwa omutwe okutambula obutasalako, okutali kwa kifo ekiruma ne bw’oba ogalamidde, oba okweyongera nga ogalamidde, teebereza ebizibu bibiri eby’obulabe ebiva ku kuzimba emisuwa gya Monro-Kellie:
3. Subdural Hematoma (SDH) okuva mu kukutuka kw’emisuwa gy’obwongo egyagoloddwa (\(10\%\) okutuuka ku \(25\%\) ku balwadde ba SIH).
4. Cerebral Venous Sinus Thrombosis (CVST) okuva mu kuyimirira kw’emisuwa munda mu nnyindo ezijjudde, ezikulukuta mpola (\(2\%\) ku balwadde ba SIH).
5. TOkola Diagnostic Lumbar Puncture simply to "Okukebera Puleesa y'okuggulawo Entono" mu Suspected SIH.
6. Ebitundu 60 ku 65 ku buli 100 eby’abalwadde abalina Puleesa y’omu mutwe (Spontaneous Intracranial Hypotension) ekakakasiddwa balina puleesa y’okuggulawo okufumita kw’omugongo eya NORMAL ddala (\(6\text{ okutuuka ku }20\text{ cmH}_2\text{O}\)) kubanga SIH buzibu bwa obunene bwa CSF obutono, si kituufu nti puleesa ya CSF entono mu mbeera ya lateral decubitus.
7. Okukola okufumita omugongo okuteetaagisa okuzuula ekituli kifumita ekituli ekipya mu lumbar dura, ne kyongera okukulukuta kwa CSF kw’omulwadde. Wabula, okuzuula SIH mu ngeri etali ya kuyingirira nga okozesa Contrast-Enhanced Brain MRI ne Whole-Spine T2 MR Myelography.
8. NEVER Drain Bilateral Subdural Hygromas or Subdural Hematomas in an SIH Patient Without Sealing the Spinal CSF Leak First (or Simultaneously). Mu bitongole eby'amangu mu nsi yonna, okukung'aanya amazzi g'omugongo ku njuyi zombi ku CT y'omutwe mu muntu ow'emyaka 40 atalina buvune ku mutwe kutera okuzuulibwa obubi nga "spontaneous chronic subdural hematomas" ne kitwalibwa ekisenge omulongoosebwamu amazzi agakulukuta mu bituli ebiyitibwa burr-hole. Olw’okuba ebikuŋŋaanyizibwa ebyo eby’omu mutwe byatondebwa mu ngeri ey’obutakola okujjuza ekifo ekiri mu mutwe ekitondebwawo okukulukuta kwa CSF mu mugongo, okufulumya amazzi g’omugongo nga tokola Lumbar Epidural Blood Patch kisooka kuleeta okuddamu amangu, pneumocephalus, downward transtentorial brainstem herniation, n’okufa.
9. Tandika obujjanjabi obw'amangu obw'omutala gw'abasawo nga weetegekera eddagala eriweweeza ku musaayi ogw'ekika kya Epidural:
10. Supine Rest & Aggressive Hydration: Fuula \(1\text{ ku }2\text{ liita}\) eza \(0.9\%\) Normal Saline IV (oba \(2.5\text{ okutuuka ku }3\text{ liita/olunaku}\) ez'amazzi ag'omu kamwa).
11. Caffeine mu misuwa oba mu kamwa: Muwe Caffeine Sodium Benzoate \(500\text{ mg}\) IV mu \(500\text{ mL}\) Omunnyo ogwa bulijjo ogufukiddwa mu ddakiika 60 (gwenkana \(250\text{ mg}\) eya caffeine atalina mazzi), oba \(200\text{ okutuuka ku }300\text{ mg}\) ya Caffeine ow’omu kamwa buli ssaawa 6 ku 8 (okwewala okukozesa ddoozi ez’akawungeezi). Caffeine aziyiza adenosine \(\text{A}_1/\text{A}_2\) receptors okuzzaawo okugaziwa kw’emisuwa gy’obwongo egy’okuliyirira okuluma era n’asitula choroid plexus \(\text{Na}+/\text{K}+\text{-ATPase}\) okukola CSF.
12. Abdominal Binder when Upright: Okusiiga snug elastic abdominal binder nga tonnayimirira kisitula puleesa y’omusuwa gw’omu lubuto mu lubuto ne epidural venous plexus, ekikendeeza ku orthostatic CSF siphon.
13. Kola Autologous Epidural Blood Patch (EBP) (\(20\text{ okutuuka ku }40\text{ mL}\) y'omusaayi gw'emisuwa ogutaliimu) nga Definitive First-Line Rescue.
14. Ku bulumi bw’omutwe oluvannyuma lw’okufumita (PDPH) oluvannyuma lw’okubudamya Omugongo/Epidural Anesthesia oba Okufumita Omugongo: Ekitundu kimu eky’omugongo Epidural Blood Patch (\(15\text{ to }20\text{ mL}\) of sterile autologous blood) ekifuyiddwa ku ddaala oba wansi w’omutendera gumu wansi w’ekifo we bafumitiddwa kiwonya abalwadde 85 ku 95 ku buli 100 mu ssaawa.
15. Ku Spontaneous Intracranial Hypotension (SIH): Kola High-volume non-targeted single- oba bi-level Lumbar/Thoracolumbar Epidural Blood Patch (\(20\text{ okutuuka ku }40+\text{ mL}\) empiso okutuusa omulwadde lw’awulira omugongo omutono/radicular fullness), n’ogobererwa essaawa 2 ku 4 ez’okukakali supine/Trendelenburg okuwummula. Singa obubonero busigala oluvannyuma lw’okukuba omusaayi emirundi 1 ku 2 egitagendereddwamu, kola Lateral Decubitus Dynamic CT Myelography oba Digital Subtraction Myelography (DSM) okulaga ekituufu Type 1 ventral spur, Type 2 root diverticulum, oba Type 3 CSF-Venous Fistula ku targeted fibrin glue patching, transvenous Onyx embolization, oba okuddaabiriza microsurgical.

Omutendera 3: Enkola Enkakafu ey’Olunyiriri olusooka: Ekitundu ky’omusaayi mu bitundu by’omubiri ebiyitibwa Autologous Epidural Blood Patch (EBP) .¶

Autologous Epidural Blood Patch (EBP) ekola okuyita mu mitendera ebiri egy’enjawulo: 1. Omutendera ogw’amangu (Eddakiika 0 okutuuka ku 30: Mass Effect): Okufuyira \(20\text{ okutuuka ku }40\text{ mL}\) omusaayi mu kifo ky’omugongo kinyigiriza ensawo y’omugongo, ne kisengula CSF y’omugongo esigadde waggulu mu mutwe n’okulengejja obwongo obuseeyeeya okuva ku bizimbe ebiwulira obulumi. 2. Omutendera ogulwawo (Essaawa 6 ku 48: Fibrin-Platelet Plug): Omusaayi ogw’okwetongola oguzibikira gunywerera ku dura mater eyakutuse, ne guvaako okukula kw’ebiwuziwuzi (fibroblast proliferation) n’okuteekebwa kwa kolagini okusiba amaziga.

• Obukodyo obw'omutindo ku PDPH vs. SIH:
• Mu Iatrogenic PDPH (Known Lumbar Puncture Site): Nga okozesa enkola ya double-operator sterile (omusawo omu ng’atuuka mu kifo ky’omugongo ku oba ekifo kimu wansi w’okuboola kw’omugongo okwasooka; owookubiri ng’aggya omusaayi omuggya ogw’emisuwa ogutaliimu buwuka okuva mu mukono), mpola mpola empiso \(15\text{ okutuuka ku }20\text{ mL}\) ey’omusaayi ogw’ekika kya sterile autologous mu epidural ekifo, okuyimirira singa omulwadde aloopa puleesa y’omugongo ey’amaanyi oba obulumi mu bitundu by’omubiri.
• Mu Spontaneous Intracranial Hypotension (SIH): Olw’okuba amaziga agava mu kifuba gatera okuba ag’omu kifuba oba ag’omumwa gwa nnabaana, ebiragiro ebikkiriziganya (Cheema/Anderson et al. 2023) bigamba nti obuzito obw’amaanyi obutagendereddwamu Lumbar oba Bi-Level (Thoracolumbar + Lower Lumbar) Epidural Blood Patch of \(20\text{ okutuuka ku }40+\text{ mL}\) wansi w’obulagirizi bwa fluoroscopic oba CT, nga zigobererwa essaawa 2 ez’okuwummula okw’amaanyi mu tulo oba Trendelenburg (\(-5\text{ degrees}\)) etali ya maanyi.

Omutendera 4: Okukebera Myelography okw'omulembe ku Refractory SIH n'okutegeera "Rebound Intracranial Hypertension (RIH)".¶

1. Ddi lw'olina okulagira enkola ya Dynamic CT Myelography (DCTM) oba Digital Subtraction Myelography (DSM):
2. Singa obulumi bw’omutwe obutereevu bulemererwa okugonjoola oluvannyuma lwa 1 ku 2 ez’obuzito obw’amaanyi obutagendereddwamu Epidural Blood Patches, kola myelography ey’enjawulo eteekeddwa okusinziira ku oba Spine MRI yalaga Spinal Longitudinal Extradural Collection (SLEC):
   • SLEC-Positive ku Spine MRI (Type 1 Ventral Tear oba Type 2 Proximal Tear): Kola Prone Dynamic CT Myelography / DSM ng’ebisambi biwanvuye okukwata contrast jetting okuva mu ventral calcified disc microspur tear, n’ogobererwa Targeted Transforaminal Epidural Blood + Fibrin Glue Patching oba Okulongoosa mu ngeri ya Microsurgical Ventral Dural Repair.
   • SLEC-Negative ku Spine MRI (Type 3 CSF-Venous Fistula oba Distal Lateral Diverticulum): Kola Right and Left Lateral Decubitus Dynamic CT Myelography oba DSM mu kiseera ky’okufuuwa okuziyiza era ojjanjabe CSF-Venous Fistula mu ngeri enkakafu ne Endovascular Transvenous Onyx Embolization of the paraspinal omusuwa ogufulumya amazzi (90% omuwendo gw’okuwona), CT-Guided Fibrin Glue Occlusion, oba Okulongoosa okusiba ebikoola by’obusimu.
3. Okutegeera Post-Patch "Rebound Intracranial Hypertension (RIH)" (20% ku 30% ku balwadde ba SIH abawonye):
4. Mu kiseera ky’okukulukuta kwa CSF okukola, ekitundu ky’omubiri ekiyitibwa choroid plexus upregulates CSF production. Oluvannyuma lw’okukulukuta kw’omugongo okusibwa nga kuggaddwa n’akatundu k’omusaayi oba Onyx embolization, obuzito bwa CSF busukka okumala akaseera, ekivaako Rebound Intracranial Hypertension (RIH) mu ssaawa 4 ku 48.
5. Engeri y'okutegeera RIH ng'oggyeeko ekitundu ky'omusaayi ekiremye: Ekitundu ky'omusaayi ekiremye kireeta okulumwa omutwe mu kitundu ky'omutwe (occipital headache) nga kino kisingako awo ng'oyimiridde n'owummuzibwa nga kipapajjo. Rebound Intracranial Hypertension ereeta frontal/retro-orbital headache nga ESINGA OBUBBI nga ogalamidde ekiro era ETEREZA ng’otudde oba ng’oyimiridde nga weegolodde.
6. Obujjanjabi bwa RIH: Situla omutwe gw’ekitanda okutuuka ku \(30\text{ degrees}\), okugumya omulwadde nti RIH ekakasa okuggalawo okukulukuta okulungi, era omuwandiike Oral Acetazolamide (Diamox, \(250\text{ okutuuka ku }500\text{ mg}\) emirundi ebiri oba esatu buli lunaku) okumala wiiki 1 ku 4.

Ennamba z‟amangu mu bitundu n‟ebiragiro by‟obujjanjabi¶

Ebibuuzo ebitera okubuuzibwa¶

Lwaki omutwe ogulumwa mu Spinal CSF Leak gubula ddala nga gugalamidde ne gudda mu ddakiika ntono ng’oyimiridde?¶

Mu budde obwa bulijjo, obwongo bwo obuzitowa gulaamu 1,400 butengejja awatali buzito munda mu mazzi g’omu bwongo (CSF) aga mililita 150, ne bukendeeza ku buzito bwabwo obukola obulungi ebitundu 97 ku buli 100 nga buyita mu kubuuka. Amaziga oba fistula mu spinal dura bwe gakulukuta omutto ogwo ogw’amazzi, okuyimirira oba okutuula nga weegolodde kireetera gravity okusiphon CSF esigadde wansi mu mugongo ogwa wansi. Awatali mutto gwabwo ogukulukuta, obwongo buseeyeeya wansi nga bugenda ku musingi gw’ekiwanga, ne busika ku dura mater ewunyiriza obulumi, ekwata emisuwa n’obusimu bw’omutwe. Akaseera k’ogalamira ddala ku mugongo (diguli 0), amaanyi ag’ekisikirize galekera awo okusika amazzi mu mugongo, CSF n’ekulukuta n’edda okwetooloola obwongo, era omutwe ogw’okusika gubula mu ddakiika 15 ku 30.

Lwaki kitta okulongoosa okufulumya amazzi mu bilateral Subdural Hematomas mu mulwadde alina SIH nga tonnaba kukola Epidural Blood Patch?¶

Abalwadde abawera ebitundu 25 ku buli 100 abalina Spontaneous Intracranial Hypotension bafuna okukuŋŋaanyizibwa kw’amazzi (hygromas) oba okuzimba omusaayi (subdural hematomas) ku njuyi zombi ez’obwongo bwabwe kubanga obwongo obuseeyeeya wansi bukutula emisuwa emitonotono egy’omuggalo ate amazzi ne gajjuza ekifo ekitaliimu mutwe. Singa omusawo w’obusimu asima ebituli by’obusimu mu kiwanga okufulumya amazzi mu bifo ebyo ebikuŋŋaanyiziddwa wansi w’omugongo ng’okukulukuta kw’omugongo kukyasonseka nnyo CSF ​​wansi, okuggulawo ekiwanga kiraga waggulu w’obwongo ku puleesa y’empewo ate ng’okukulukuta kw’omugongo kusika okuva wansi. Ekyuma ekyo ekya puleesa kisika ekikolo ky’obwongo ekiserebye butereevu wansi nga kiyita mu kifo ekiggule (tentorial opening), ne kireeta okuwunya kw’ekikolo ky’obwongo okutakyuka n’okukoma. Okukola Lumbar Epidural Blood Patch kusooka kusiba ekisenge ky’omugongo, ekisobozesa obulwadde obusinga obungi obwa SIH subdural hematomas okuddamu okunyiga awatali kulongoosebwa bwongo.

"CSF-Venous Fistula" (Type 3 Leak) kye ki, era lwaki Spine MRI eya bulijjo ya bulijjo ddala ng'olina?¶

Yasooka kunnyonnyolwa Schievink ne banne mu 2014, CSF-Venous Fistula (CVF) ereeta okutuuka ku kimu kya kusatu ku balwadde bonna aba Spontaneous Intracranial Hypotension. Okwawukana ku classic dural tear (CSF gy’ekuŋŋaanya mu masavu g’omugongo era n’erabika ng’eyaka ku standard spine MRI), CSF-Venous Fistula ye microscopic short-circuit eyunga sleeve y’ekikolo ky’obusimu bw’omugongo mu kifuba butereevu mu musuwa gw’omugongo oguliraanyewo. Olw’okuba buli ttonsi lya CSF ekulukuta lisonseka butereevu mu musaayi gw’emisuwa, zero amazzi gakuŋŋaana ebweru wa dura era standard Spine MRI eringa eya bulijjo 100 ku 100. Okuzuula CSF-Venous Fistula kyetaagisa Lateral Decubitus Dynamic CT Myelogram oba Digital Subtraction Myelogram, era ewona nga osiba omusuwa ogufulumya amazzi ne Onyx glue ow’amazzi oba okulongoosebwa.

Lwaki omutwe gwange gwasenguka ne gugenda mu maaso g’omutwe ne gutandika okunnuma ennyo nga ngalamidde olunaku olwaddirira Epidural Blood Patch yange?¶

Ekyo ekituufu eky’okukyusakyusa mu nneeyisa y’okulumwa omutwe, okuva ku kulumwa omutwe emabega w’omutwe ogukuluma ng’oyimiridde okutuuka ku mutwe ogw’omu maaso ogukuluma ennyo ng’ogalamidde, guyitibwa Rebound Intracranial Hypertension (RIH) era gukakasa nti Epidural Blood Patch yo yasobola okusiba okukulukuta kwo okwa CSF. Nga omugongo gwo gukulukuta amazzi, choroid plexus yo yayongera okukola CSF mu overdrive. Ekitundu ky’omusaayi bwe kimala okuziba ekituli, okukola CSF okwo okw’enjawulo kujjula ekiwanga okumala akaseera okumala ennaku ntono okutuuka ku wiiki. Okwebaka ng’omutwe gw’ekitanda kyo guwaniridde ku diguli 30 n’okumira eddagala lya Acetazolamide (Diamox) eriweebwa mu kamwa mu kaseera katono kimalawo omutwe ogw’amaanyi ogw’okuddamu ate nga thermostat yo eya CSF eddaamu.
