[DeBakey IIIb type dissecting aneurysm with adrenal myelolipoma; report of a case].

We report a case of DeBakey IIIb type dissecting aneurysm with adrenal myelo-lipoma in a 50-year-old woman. The patient was referred to our hospital for severe back pain with severe hypertension. The chest computed tomography (CT) scans and aortography showed the DeBakey IIIb type dissecting aneurysm. And the round-shaped masses on her both side adrenal glands were detected by abdominal CT scans. First, the thoracic aneurysm was replaced with a 26 mm woven dacron graft under cardiopulmonary bypass. Six months later a right adrenal tumor was removed under a postero lateral approach. Her postoperative course was uneventful. And her blood pressure control was good with no antihypertensive drug. Pathological findings for the resected tumor was diagnosed as myelolipoma. To our knowledge, a dissecting aneurysm with adrenal myelolipoma has not been previously reported.
