[Giant and bilateral adrenal myelolipoma. Case report]

Abstract

The adrenal myelolipoma is a relatively rare benign tumour of adipose cell and bone marrow elements, non functioning and asymptomatic. Giant and bilateral adrenal myelolipoma is quite rare. The Authors report a case of bilateral adrenal myelolipoma, a giant one (> 15 cm) on the left side and a small one (> 4 cm) on the right with constant pain in a 57-year-old man, shown by computerized tomography. The hormonal blood tests were normal. Surgical excision was performed for large left symptomatic mass, by open laparotomy, and biopsy for right minor adrenal lesion. Histology confirmed diagnosis of myelolipoma for both masses. Follow-up to 6-12 months did'nt show any change of the right myelolipoma. The authors agree with the need to remove the giant adrenal myelolipoma, because the lesion > 10 cm have a high risk of cancer and hemorrhagic complication, while for small myelolipoma (< 6 cm) 6-12 months follow-up is the appropriate choice.
