Renal cell carcinoma in allograft kidney--a case report with unusual findings at autopsy.

A 30-year old male who had a non-related cadaveric renal transplant at the age of 12 years, presented with generalised CNS symptoms and meningeal enhancement on CT scan of the brain, 18 years after the transplantation. Autopsy revealed renal cell carcinoma in the transplanted kidney and metastatic tumour in a variety of organs including the brain. Prior ultrasound scans done at various post-transplant periods had all been normal.
