Acute subdural hematoma (ASDH) without subarachnoid or intracerebral hemorrhage following rupture of an intracranial aneurysm is rare. Only 34 cases of pure ASDH resulting from rupture of an intracranial aneurysm, and 5 cases of pure ASDH secondary to rupture of an anterior cerebral artery (ACA) aneurysm, have been reported in the literature. We report a case of a patient with a ruptured distal ACA aneurysm who presented pure ASDH on CT. ⋯ Evacuation of the subdural hematoma, with the clipping of the aneurysm was performed. Intraoperatively, adhesion between the dome of aneurysm and the falx cerebri was observed. The patient was discharged from the hospital without neurological deficits.
