The most common cause of subarachnoid hemorrhage at the period of pregnancy and during puerperium is rupture of an intracranial aneurysm. It is five times more common in pregnant women than in non-pregnant women. This pathology is more common in primiparous women and in the third trimester of pregnancy. A 37-year-old woman who was admitted to the emergency department with sudden-onset headache and loss of consciousness was diagnosed with intracranial hemorrhage due to middle cerebral artery aneurysm rupture. The patient, who gave birth with emergency cesarean delivery, underwent surgery for subarachnoid hemorrhage. The case is presented here because of its rarity.
