Unilateral asymptomatic adrenal tuberculoma: the role of percutaneous biopsy.

We report the case of a 55-year-old male with a large left adrenal mass that conformed to the normal shape of the adrenal gland. Percutaneous biopsy revealed tuberculosis and, following anti-tuberculosis therapy, there was a >75% decrease in the size of the mass. In large tumefactions of the adrenal glands in which a normal adrenal contour is maintained, a percutaneous biopsy may obviate the need for major intervention.
