Fulminant Reversible Cerebral Vasoconstriction Syndrome in Breakthrough COVID 19 Infection.

ABSTRACT

COVID 19 infection continues to afflict people worldwide. Neurological complications of COVID infection are common. We report a case of fulminant reversible cerebrovascular constriction syndrome (RCVS) in a patient with breakthrough COVID 19 infection who was fully vaccinated. A 64 year old lady, fully vaccinated 2 months back, presented with headache, drowsiness, partial seizures, visual impairment and quadriplegia. Her nasopharyngeal swab was tested positive for SARS COV2 on real time PCR assay. MRI brain FLAIR images showed multifocal hyperintensities with MR angiogram showing arterial vasoconstriction suggestive of RCVS. Despite initiation of nimodipine, patient's symptoms worsened and she succumbed to sepsis. RCVS following COVID infection has been reported to have a benign outcome. However, despite vaccination, fulminant RCVS following a breakthrough COVID infection was observed in our patient.
