[Unilateral adrenal tuberculosis: a case report].

Computed tomography (CT) performed for a 75-year-old man as a follow-up examination for deep vein thrombosis in October 2010 revealed a left adrenal mass (diameter, 8 mm). In December 2012, the adrenal mass increased to 28 mm in diameter, and he was referred to our department. Several blood examinations revealed that the adrenal mass was non-functioning, and only peripheral lesions were observed to be enhanced by using CT in the arterial phase. Malignancy was suspected due to the irregular shape and growth of the mass, and left adrenalectomy was performed in February 2013. The histopathological diagnosis was adrenal mycobacteriosis, and clinical diagnosis was adrenal tuberculosis. No other tuberculosis infection-related lesion was detected, and the patient was treated with multidrug antituberculous chemotherapy.
