Brain metastases are the most common intracranial malignancy in adults and may occasionally deposit within a pre-existing primary brain neoplasm.
We describe, in two directly related family members, the rare occurrence of renal cell carcinoma (RCC) metastasis to haemangioblastoma (HB) in the context of Von Hippel-Lindau syndrome. Detection of this phenomenon can be marred by histological overlap between RCC and HB and therefore careful histological examination, and consideration of supportive immunohistochemistry, is required when examining all HB resections. Metastatic RCC to HB upstages a primary RCC and is clinically diagnostic of Von Hippel-Lindau syndrome.
