Abstract
We describe the case of a 10-year-old boy who developed reversible cerebral vasoconstriction syndrome (RCVS) after cerebellitis. He received intravenous immunoglobulin and methylprednisolone to treat the cerebellitis. However, he then presented with a sudden severe headache, vomiting, and generalized tonic-clonic seizure. Brain magnetic resonance angiography (MRA) initially revealed diffuse cerebral vasodilatations, and diffuse multifocal segmental vasoconstrictions developed several days later. His clinical symptoms gradually resolved after several days, in the absence of any specific therapy. MRA performed 46days after symptom onset showed that the multifocal segmental vasoconstrictions had resolved, suggesting a diagnosis of RCVS. The imaging features of RCVS include multifocal segmental vasoconstriction. However, our case suggests that diffuse cerebral vasodilatation may in fact be evident during the early stage of disease.
