Infracallosal Aneurysm Rupture Revealed by Chronic Subdural Hematoma: A Case Report

Abstract
Chronic subdural hematoma (CSDH) is one of the most common entities seen in neurosurgery. We report a case of infracallosal aneurysm revealed by CSDH in a 52 years old woman. She presented 3 days alteration of consciousness in 2019 and repeated in September 2020 a severe headache and dizziness. There was no history of others symptoms, nor head trauma. Routine blood examination and coagulation profile were normal. Emergency computed tomography (TC) showed a left temporoparietal-occipital CSDH. Cerebral Angio CT found a bilobated of A2 aneurysm. The precallosal interhemispheric approach was made and clipping the aneurysm after evacuation of CSDH without complication. CSDH is one of the revealed features of intracerebral aneurysm rupture.
