Retroperitoneal hemorrhage due to a ruptured adrenal myelolipoma. A case report.
Adrenal myelolipomas are usually small and asymptomatic tumors discovered incidentally. In a small number of cases, acute pain may develop secondary to intratumoral and/or retroperitoneal bleeding. We observed a large, surgically and histologically confirmed, myelolipoma of the right adrenal gland with spontaneous internal and external hemorrhage. CT demonstrated heterogeneity of the mass, obliteration of the surrounding fat planes, and retroperitoneal blood dissection. A literature review produced only 5 reports of ruptured myelolipoma with external hemorrhage.
