Abstract
Imaging of acute neurologic disease in the emergency department can be challenging because of the wide range of possible causes and the overlapping imaging appearance of many of these entities on nonenhanced computed tomography (CT). The key to formulating a succinct, pertinent differential diagnosis includes characterizing the pattern of abnormalities on CT and identifying key features that suggest a particular diagnosis. This article divides neurologic emergencies into 5 scenarios based on the CT findings, including subarachnoid hemorrhage, intraparenchymal hemorrhage, vasogenic edema without and with underlying mass lesion, and acute hydrocephalus. Specific common or important diagnoses in each category are discussed.
