Abstract
In a series of 24 patients with cerebellar haemangioblastoma two subsequently developed renal carcinoma and one was found to have an epididymal tumour. The association between renal carcinoma and cerebellar haemangioblastoma is discussed. Repeated investigation of the genitourinary tract is advised in all cases of cerebellar haemangioblastoma to detect renal carcinoma before metastases have developed.
