RESUMO
Adrenocortical carcinoma (ACC) is a rare malignancy that often carries a poor prognosis whereas adrenal incidentalomas are relatively common findings on imaging. Although most adrenal lesions are benign, 15% of patients with ACC are diagnosed based on workup for an adrenal incidentaloma. Continued surveillance or surgical resection may be recommended depending on size. The risk of a benign, non-functional adrenal lesion becoming malignant is low. Therefore, adrenal lesions typically undergo surveillance for no more than 2 years in patients with stable findings and no history of malignancy. This case describes a young adult female with a benign left adrenal adenoma who was found to have high grade ACC 7 years later. Based on interval size increase with indeterminate density, patient underwent surgical resection with adjuvant radiation and medical therapy.
