Imaging Findings of Intracranial Hypotension Presented with Pseudo-Subarachnoidal Hemorrhage

Abstract

Spontaneous intracranial hypotension (SIH) is a condition in which the fluid pressure inside the skull is lower than normal. It is secondary to cerebrospinal fluid (CSF) leak at the level of the spine and the resulting loss of CSF volume. Pseudo-subarachnoidal hemorrhage is a rare condition that can occur in patients with spontaneous intracranial hypotension. The diagnosis is very important because it can be confused with true subarachnoidal hemorrhage. True subarachnoidal hemorrhage is one of the complications that may occur in SIH patients. The differentiation of these two conditions as well as computed tomography (CT) and magnetic resonance imaging (MRI) findings and the response of the blood-patch treatment applied by interventional radiology is also very valuable.

Yalancı-Subaraknoid Kanama ile Prezente Olan İntrakraniyal Hipotansiyonun Görüntüleme Bulguları

Abstract

Spontan intrakraniyal hipotansiyon (SIH), kafatasının içindeki sıvı basıncının normalden düşük olduğu bir durumdur. Omurga seviyesinde beyin omurilik sıvısı (BOS) sızıntısına ve bunun sonucunda BOS hacim kaybına sekonder gelişir. Psödo-subaraknoidal kanama, spontan intrakraniyal hipotansiyonu olan hastalarda görülebilen nadir bir durumdur. Tanı çok önemlidir çünkü gerçek subaraknoidal kanama ile karıştırılabilir. Gerçek subaraknoidal kanama SIH hastalarında ortaya çıkabilecek komplikasyonlardan biridir. Bu iki durum arasındaki farkın bilgisayarlı tomografi (BT) ve manyetik rezonans görüntüleme (MRG) bulguları ve girişimsel radyoloji tarafından uygulanan kan-yama tedavisinin yanıtı çok değerlidir.
