Reversible cerebral vasoconstriction syndrome presenting as convexity subarachnoid hemorrhage and posterior reversible encephalopathy syndrome during postpartum: A case report and literature review

ABSTRACT

@#Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by thunderclap headache and reversible cerebral vasoconstriction, with other neurologic signs and symptoms. To the best of our knowledge, there were only a few cases of RCVS presenting both as both convexity subarachnoid hemorrhage (cSAH) and posterior reversible encephalopathy syndrome (PRES). Herein, we report a case of a 32-year-old woman with RCVS who presented with recurrent thunderclap headaches that occurred 50 days after delivery, with cSAH and PRES on magnetic resonance imaging (MRI). She had significant clinical and radiological recovery on 3 months’ follow-up. The clinical coexistence of cSAH and PRES in our case with RCVS is quite rare. This case illustrates the importance of awareness of the diagnosis of RCVS among clinicians even when initial brain and vascular imaging are normal. Early diagnosis and treatment are crucial for better prognosis.
