Postinfectious coronavirus disease 2019 hemorrhagic cerebellitis: Illustrative case


Advocate Lutheran General Hospital


Background: Conditions that can mimic posterior fossa tumors are rare. Their identification is crucial to avoid unnecessary surgical intervention, especially when prompt initiation of medical therapy is critical.

Observations: The authors presented a case of pseudotumoral hemorrhagic cerebellitis in a 3-year-old boy who presented initially with headache, persistent vomiting, and decreased level of consciousness 9 weeks after severe acute respiratory syndrome coronavirus 2 infection. Magnetic resonance imaging showed a left cerebellar hemorrhagic mass-like lesion with edema and mild hydrocephalus. The patient responded to high-dose steroids and was discharged 2 weeks later with complete recovery.

Lessons: When evaluating patients with possible tumor syndromes, it is important to also consider rarer inflammatory syndromes that can masquerade as neoplasms. Postinfectious hemorrhagic cerebellitis is one such syndrome.
