[Using ultrasound investigation in differential diagnosis of adrenal malignant tumors].

Possibilities of ultrasound investigation (USI) application for differential diagnosis of the suprarenal glands tumors (SGT) were studied. USI was conducted in 169 patients with SGT, including 95 with malignant tumors of suprarenal glands (MTSG) and 64--with benign SGT. USI constitutes the main method of screening, permitting to reveal SGT in 90.5% of patients. Diagnostic criterions of MTSG were: diameter of tumor exceeding 10.1 cm, incorrect form, irregular edges, presence of invasion, lymphadenopathy, regional and remote metastases. In 45.3% of observations it was possible to establish the MTSG diagnosis, using USI.
