ABSTRACT

ABSTRACT Spontaneous intracranial hypotension (SIH) is a syndrome that was unknown until the advent of magnetic resonance imaging (MRI). It is a cause of orthostatic headache, which remains underdiagnosed and, rarely, can result in several complications including dural venous sinus thrombosis, subdural hematoma and subarachnoid hemorrhage. Some of these complications are potentially life-threatening and should be recognized promptly, mainly by imaging studies. We reviewed the MRI of nine patients with SIH and describe the complications observed in three of these patients. Two of them had subdural hematoma and one had a dural venous sinus thrombosis detected by computed tomography and MRI. We concluded that MRI findings are of great importance in the diagnosis of SIH and its complications, which often influence the clinical-surgical treatment of the patient.


RESUMO Hipotensão Intracraniana Espontânea (HIE) é uma síndrome desconhecida até o advento das imagens de Ressonância Magnética (RM). É uma causa de cefaleia ortostática que permanece subdiagnosticada e raramente resulta em complicações, como trombose de seios venosos durais, hematoma subdural e hemorragia subaracnoidea. Algumas dessas complicações são potencialmente ameaçadoras à vida e devem ser prontamente reconhecidas pelos estudos de imagem. Nós revisamos as RM de 9 pacientes com HIE e descrevemos as complicações observadas em 3 casos. Dois deles tiveram hematoma subdural e um teve trombose de seio venoso dural detectados por tomografia computadorizada e RM. Concluímos que achados de RM são de grande importância no diagnóstico de HIE e suas complicações, frequentemente influenciando o tratamento clínico-cirúrgico do paciente.

ABSTRACT

A hipertensão intracraniana (HIC) é um problema em pelo menos metade das lesões parenquimatosas e em um terço dos pacientes com lesão difusa. Metade dos pacientes que desenvolvem HIC morrem, a despeito da descompressão cirúrgica ou outras terapias. A clínica clássica de aumento da pressão intracraniana em adultos e em crianças consiste em cefaléia, náuseas e vômitos, além de vertigem, paralisias oculares, papiledema, turvação visual e amaurose fugaz. A mensuração da pressão intracraniana e o seu manejo adequado podem auxiliar o intensivista na otimização ds terapêuticas disponíveis atualmente para melhorar o prognóstico e a qualidade de vida dos pacientes severamente acometidos por essa condição.

ABSTRACT

The authors reported a 54 year-old Italian woman with headache attributed to spontaneous low cerebrospinal pressure and normal brain magnetic resonance imaging. Lumbar puncture was done and opening pressure was not measurable. 99mTc radionuclide cysternography was used in diagnosis and demonstrated 3 lumbar leakages and early appearance of bladder activity. Epidural blood patch was performed. This option was safe and successful to treat this kind of headache without relapse of symptoms after 3 years follow-up.
