Teratoma in the region of an adrenal gland is an uncommon retroperitoneal tumour. Only a few cases — mostly in young patients — have been reported. This case report describes such a tumour in a 77-year-old man who presented with acute urine retention. Abdominal X-ray and computed tomography showed that the tumour displaced the left kidney downwards. The mass, which contained fat and had a stranding and calcified component, was excised. Intraoperatively, a large retroperitoneal lipomatous tumour encasing the left kidney but sparing other viscera was found. The lipomatous tumour was isolated within a well-defined pseudocapsule that covered most of the tumour, encased the left kidney, and was separate from the pancreas and spleen. The adrenal gland was present at the periphery of the tumour. To our knowledge, this is the first reported case of teratoma in the region of an adrenal gland occurring in an elderly person.
