RT Book, Section A1 Cook, James Steven A2 Salardini, Arash A2 Biller, José SR Print(0) ID 1127045104 T1 Some Common Neurological Emergencies T2 The Hospital Neurology Book YR 2016 FD 2016 PB McGraw-Hill Education PP New York, NY SN 9780071845830 LK neurology.mhmedical.com/content.aspx?aid=1127045104 RD 2024/03/28 AB Increased intracranial pressure (ICP) often requires invasive monitoring and emergent treatment. Pseudotumor cerebri is the common name for the idiopathic form, which may be due to cerebral venous sinus thrombosis and associated with papilledema and visual loss. The opposite clinical syndrome is intracranial hypotension, which is one of the causes of new daily persistent headache. The magnetic resonance imaging (MRI) shows a sagging brain and pachymeningeal enhancement. Myelography using either computed tomography (CT) or MRI imaging is used to find the cerebrospinal fluid (CSF) leak, sometimes cured with a blood patch. Brain herniation is a complication of increased ICP requiring emergent treatment. False localizing signs are seen due to compression of the contralateral Kernohan notch.
