Abstract

Adrenal myelolipoma is rare, hormone inactive, benign tumor composed of mature adipose tissue and hematopoietic tissue. From 1996 to 2009, 5 patients were operated for adrenal myelolipoma in Jikei University Hospital. Two of them were male and 3 were female. Mean age was 58.4 years old. The tumors were located in the right adrenal in 4 and the left adrenal in 1 patient and mean tumor size was 7.8 cm. Typical imaging features were distinct hyper echoic mass on ultrasonography and intratumoral fatty element by computed tomography and magnetic resonance imaging. All five tumors were removed surgically and myelolipoma was histologically confirmed. Generally, symptomatic tumors, tumors larger than 5 cm with suspected malignancy or tumors larger than 10 cm with possibility of spontaneous rupture should be excised surgically. Asymptomatic small tumors should be observed carefully.
