title: Presacral myelolipoma: case report with computed tomographic and angiographic findings.
abstract: A rare case of presacral myelolipoma in an otherwise healthy 53 year old man is described. His only complaint was lower abdominal discomfort. Full investigation including computed tomography and angiography revealed a well-delineated, heavily calcified, avascular retrorectal mass adhering to the presacral fascia. Histologically the mass showed a mixture of haemopoietic tissue and mature fat cells. Clinically the absence of symptoms and bone involvement served to distinguish this condition from other more sinister presacral lesions, particularly a chordoma.
