title: M5 segment aneurysm presenting as "pure acute SDH".
abstract: Spontaneous "pure acute subdural hematoma (SDH)" is arguably a rare condition. We report on a pregnant female patient presenting as spontaneous acute SDH without subarachnoid hemorrhage (SAH) due to rupture of distal (M5 segment) middle cerebral artery aneurysm. We hereby discuss the diagnostic dilemma of this rare condition, along with the need for watchful evaluation of acute SDH without preceding head injury presenting in emergency outpatient departments, especially when it is first encountered by a trainee resident.
