A 65-year-old man with no medical history developed intermittent vertigo, progressively worsening headaches, and morning nausea. MRI found an enhancing mass in his right cerebellar hemisphere. The pathology came back as desmoplastic medulloblastoma, a WHO grade 4 tumor, in a case reported in the International Journal of Surgery Case Reports.
Medulloblastoma is a tumor pediatric neuro-oncologists see constantly. It is the most common malignant brain tumor of childhood. In adults, it makes up 0.4 to 1 percent of central nervous system tumors, mostly in people under 40. Cases past 60 are rare enough that each one gets written up.
