Angiomyolipoma of the Adrenal Gland: A Case Presentation and a Review of Adrenal Lipomatous Tumors

Angiomyolipoma (AML) is a typically benign renal tumor derived from mesenchymal tissue. Extrarenal occurrences of AML are possible, but the adrenals are an exceedingly rare site. To date, a total of 4 cases of adrenal AML have been documented in the English literature.1–3 We present a case of right-sided adrenal AML found in a patient who initially presented with right-sided flank pain. Differential diagnosis of adrenal masses should include lipomatous tumors, as operative considerations and prognoses can be drastically altered.
