Adrenal myelolipoma (AM), with its unique histological appearance, is a rarely encountered benign tumor. It is mostly asymptomatic and is incidentally detected. Rarely, in some large masses, retroperitoneal hemorrhage, which could cause lifethreatening shock due to spontaneous rupture of AM may develop. In this case report, we presented a 60-year-old male patient who was admitted with abdominal pain and rapid decline in hemoglobin values. Computed tomography (CT) showed bleeding into the retroperitoneal space secondary to the rupture of myelolipoma measuring 14-cm in diameter in the right adrenal gland. Emergency exploratory laparotomy was performed, and the mass was excised. The possibility of rupture and bleeding of large adrenal myelolipomas should be taken into consideration and accordingly, follow-up of asymptomatic patients should be done carefully.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
