An Adult Case of Acute EBV Cerebellitis

Acute neurological manifestations of infectious mononucleosis are uncommon and have been predominantly reported in the paediatric population. We report a case of acute Epstein-Barr virus cerebellitis in an adult in whom spontaneous resolution of symptoms and signs occurred after 2 weeks of supportive treatment. An infective cause for an acute cerebellar syndrome in an adult must always be considered in the differential diagnosis when appropriate. LEARNING POINTS: A high index of suspicion is needed in adults who present with a febrile syndrome and cerebellar signs. An acute cerebellar syndrome may be the only manifestation of Epstein-Barr virus infection. In certain cases, conservative management may be sufficient depending on the clinical severity.
