Introduction:

Adrenal myelolipomas are unusual slow-growing benign tumors, composed of mature adipose tissue and hematopoietic cells.

Objective:

To present a new case of adrenal myelolipoma as well as to describe its clinical, imaging and applied therapeutic characteristics. Clinical Case: Female patient of 68 years old, with a history of hypertension, diabetes mellitus type 2 and obese, who was admitted to the General Surgery Service of the Hospital Militar Central Dr. Carlos J. Finlay, for presenting pain in the right hypochondrium. In the general physical examination, she presented a morbid obesity with a slight icteric dye of the skin and mucous membranes, and in the abdomen diffuse abdominal pain was observed, predominantly in the right hypochondrium without peritoneal reaction and negative Murphy sign; no palpated visceromegalias. Bi-basal crackles were heard in the thorax with diminished vesicular murmur. The blood tests performed showed liver tests with high values, and accelerated erythrosedimentation. In the computerized axial tomography an abdominal tumor was observed that impressed to correspond with the right adrenal gland, and that it mediates 110x135x90 mm. The right adrenalectomy was performed without complications. The histopathological diagnosis was an adrenal myelolipoma. The patient has evolved satisfactorily.

Conclusions:

Adrenal myelolipoma does not present a characteristic clinical picture, so its finding is often incidental. Computed tomography is the technique of choice for the diagnosis of this lesion. In the masses greater than 6 centimeters, surgical treatment is indicated, with conventional surgery being a useful route for this.
