Abstract 092: Intracranial Aneurysm Rupture Presenting as Isolated Subdural Hematoma

A 34‐year‐old female with atraumatic history presented with sudden‐onset headache and bilateral hand paresthesia. CT and CTA revealed a retroclival subdural hemorrhage. MRA showed a 6 mm right posterior communicating (PCom) artery aneurysm abutting the dura. The patient was treated with coil embolization and recovered in the ICU. This rare presentation of aneurysmal rupture into the subdural space highlights the need to consider aneurysmal causes in atraumatic subdural hematoma to prevent future catastrophic rebleeding. image image
