Abstract

|
An 83 year-old man was admitted to our hospital for management of a comatose mentality after hemodialysis. Computed tomographic angiography showed acute subdural hematoma (SDH) in both cerebral convexities with arterial bleeding. Subdural hematoma is usually caused by trauma. However, acute spontaneous subdural hematoma (ASSDH) of arterial origin without traumatic history is has been rarely reported. Although non-traumatic subdural hematoma may be caused by coagulopathy, arteriovenous malformation or ruptured aneurysm, the possibility of the cortical artery origin should be considered in case of spontaneous SDH. Computed tomographic angiography can help to identify the bleeding focus of the arterial origin, and to make a differential diagnosis from other origins.
