Reversible Cerebral Vasoconstriction Syndrome with Subarachnoid Hemorrhage and Stroke

Abstract

Reversible cerebral vasoconstriction syndrome is a complex condition characterized by temporary constriction of the brain's arteries. Diagnosis typically involves a retrospective approach, necessitating repeated imaging to confirm the resolution of cerebral arterial spasms. We describe a case of a 22-year-old female with a history of posterior circulation stroke and recurrent thunderclap headaches. On imaging, evidence of stroke, convexity subarachnoid hemorrhage, and multiple areas of stenosis and dilatation in the posterior circulation associated with normal laboratory parameters were found. The resolution of clinical symptoms and angiographic findings were noted in the follow-up. After other diagnoses are excluded, patients can be reassured about favorable prognosis.
