Sonography of the adrenal glands in chronic disseminated histoplasmosis.

In this retrospective study, the findings on abdominal sonograms in six patients newly diagnosed as having chronic disseminated histoplasmosis are reported. Five of six patients showed bilateral adrenal gland enlargement that was similar in degree from side to side. The most characteristic feature was the maintenance of a triangular shape in five glands and a cylindrical shape in two glands. Four glands had a nonspecific round or oval shape. All sonographic findings correlated well with the computed tomographic (CT) findings on each patient except that CT detected the one enlarged right adrenal gland not demonstrated sonographically. Abdominal sonography may provide the initial important clue to the diagnosis of chronic disseminated histoplasmosis.
