Imaging of Neurological Emergencies.

Imaging findings in non-traumatic, non-ischemic neurological emergencies. In this video the typical and less typical imaging findings of various neurological emergencies, including spontaneous subarachnoid and cerebral hemorrhage, brain abcess, herpes encephalitis, PRES and cerebral venous sinus thrombosis are discussed. This presentation is aimed at radiology students and residents, neurologists, intensive care and emergency physicians, and basically anyone with a heart and brain for Neuroradiology. 0:00 - Introduction 2:08 - Subarachnoid hemorrhage (SAH) 5:11 - Aneurysmal subarachnoid hemorrhage 8:41 - Perimesencephalis subarachnoid hemorrhage 10:52 - Convexity subarachnoid hemorrhage 15:37 - Spontaneous intracerebral hemorrhage (sICH) 18:20 - Primary hypertensive hemorrhage 18:57 - Cerebral amyloid angiopathy 22:35 - Arteriovenous malformation 23:12 - Cerebral venous sinus thrombosis 25:06 - Cavernoma 26:39 - Focal brain edema 27:52 - Vasogenic vs. cytotoxic edema patterns on CT 30:52 - Vasogenic edema due to brain tumor 32:22 - Brain abscess 33:44 - Posterior reversible encephalopathy syndrome (PRES) 37:37 - Herpes encephalitis 40:44 - Cerebral venous sinus thrombosis 46:58 - Hydrocephalus 48:33 - Colloid cyst and other causes of non-communicating hydrocephalus 52:08 - Communicating vs. non-communicating hydrocephalus 55:16 - Meningitis, SAH and other examples of communicating hydrocephalus 58:47 - Key Messages #radiology #neuroradiology #neurology #medicalstudent #neuroradiologist #theneuroradiologist #MRI #CT #medical #emergency #mri #radiologytechnologist #radiologyresident #brainanatomy #thrombosis #stroke
