Postpartum cerebral angiopathy presenting with non-aneurysmal subarachnoid hemorrhage and interval development of neurological deficits: A case report and review of literature

Postpartum cerebral angiopathy (PCA) is a cerebrovascular disease that occurs during the postpartum period. It is characterized by reversible multifocal vasoconstriction of the cerebral arteries. We report a patient with PCA proven by cerebral angiography that revealed multifocal, segmental narrowing of the cerebral arteries and non-aneurysmal subarachnoid hemorrhage. The patient suddenly deteriorated with focal neurological deficits on the 5 th day of hospitalization. She was treated with calcium-channel blockers and monitored with daily transcranial Doppler ultrasound. Her symptoms gradually improved and she was discharged on the 11 th day of hospitalization. At 1-month follow-up, patient was completely symptom-free with no neurological deficits.
