Fewer than 2% of patients with metastatic prostate cancer (pca) develop brain metastases. Autopsy series have confirmed the rarity of brain metastases. When present, brain metastases occur in end stage, once the pca is castrate-resistant and spread to other sites is extensive. Here, we present a rare case of a patient with pca who developed a solitary parenchymal brain metastasis as first site of relapse 9 years after radical therapy. The patient underwent craniotomy and excision of the tumour. A second recurrence was also isolated to the brain. In the literature, pca patients with brain metastases have a poor mean survival of 1-7.6 months. The patient in our case report experienced a relatively favourable outcome, surviving 19 months after his initial brain relapse.
