- Background: Intracerebellar schwannoma is an extremely rare disease entity with only 21 case reports described in the literature. Case Description: A 68-year-old male presented with chronic headaches, dizziness, gait imbalance, and incoordination. Previous MRI had revealed a cystic lesion in the right cerebellum; however, patient was lost to follow-up. Updated MRI revealed dramatic enlargement of the lesion in addition to worsening clinical status. The patient underwent successful surgical resection. Conclusion: Intracerebellar schwannoma can be challenging to diagnose preoperatively due to its rare occurrence; however, it should be included in the differential diagnosis of cystic lesions in the cerebellum, and most cases can be successfully treated with complete surgical resection. Pathological examination revealed a spindle cell neoplasm with other typical histopathological features of schwannoma.
