OBJECTIVE (1) To determine the frequency of CT mimics of subarachnoid hemorrhage (SAH) in a large cohort of subjects with spontaneous intracranial hypotension (SIH). (2) To emphasize the distinctive radiologic features of SIH. PATIENTS AND METHODS CT scans of 95 subjects with SIH were retrieved and reviewed to search for findings of pseudo-SAH (CT mimics of SAH in the absence of blood). RESULTS Pseudo-SAH radiologic findings (increased attenuation in the basilar cisterns, sylvian fissures… CONTINUE READING
