(Purpose) We report five cases of adrenal myelolipoma with surgical treatment, and analyze the patients' background and clinical courses.
(Patients and methods) From 2004 to 2017, five patients diagnosed adrenal myelolipoma were underwent surgical treatment at our hospital. We investigate the patients' background and clinical courses retrospectively.
(Results) Median age was 53 years old. Four of them were male and one was female. The tumor was located on the right side in four cases and the left side in one case. All cases were incidentally found by abdominal ultrasound or computer tomography (CT) during a medical check or image examination for other disease. Whereas all cases were asymptomatic, they have past history either hypertension, diabetes or obesity. The tumor size at the time of diagnosis was from 28 mm to 80 mm (median 58 mm). All tumors were nonfunctioning, and diagnosed by CT scan preoperatively. The median tumor size at the time of operation was 66 mm.
(Conclusion) We report five cases of adrenal myelolipoma treated surgically. The opportunity of encountering this disease has been increasing as the recent improvement of diagnostic imaging such as CT, MRI, and etc. However, there is no widely-accepted treatment algorithm. We should manage them carefully, because spontaneous rupture of adrenal myelolipoma has been reported in some cases.
