Prostate cancer presenting as a solitary cerebellar metastasis. A case report and review of the literature.

We describe a case of a 70-year-old patient with sudden onset of gait ataxia, headache, dizziness and dysarthria. Magnetic resonance imaging revealed a solitary lesion in the left cerebellar hemisphere with strong and irregular enhancement of the contrast medium, surrounded by extensive edema. Rectal examination revealed an abnormally enlarged and stiff left prostate lobe, and ultrasound-guided transrectal biopsies showed prostate adenocarcinoma of mild differentiation. Neurosurgical intervention and histopathologic examination revealed metastatic prostate adenocarcinoma. The patient underwent orchiectomy and was given antiandrogens. He is still alive and closely followed. According to the literature, prostate cancer presenting as a solitary cerebellar metastasis is an extremely rare clinical problem.
