Altogether 34 patients with corticosteroma were examined. In 29 (85%) of them accurate topical diagnosis was established as a result of ultrasonic investigation. All erroneous results were obtained only for corticosteromas of small sizes (4 cm and less in diameter). Tumors not exceeding 4 cm in diameter were benign in 88% of cases. If tumor sizes were over 4 cm, they were malignant in 89%. The earliest possible investigation for the presence or absence of a tumor was indicated to patients with hypercorticism.

Sixty-one patients with chromaffinoma were examined by echography. Of these, 6 patients (9.8%) had extraadrenal tumors. Application of echography permitted a correct topical diagnosis to be made in 5 patients. In 2 persons, the tumor was located in Zuckerkandl's fascia, in 2 in the paraaortal ganglia at the level of the splenic vein and the left hilus renalis, and in 1 patient, it was located in the urinary bladder. In one of the cases, no chromaffinoma was found. Since the majority of extraadrenal chromaffinomas (96%) are located in the retroperitoneal space echography can successfully be used for diagnosing such tumors with the exception of intrathoracic tumors which cannot be visualized in connection with the presence of air in the lungs. In such cases use should be made of computer-aided tomography.

Altogether 23 patients were examined to assess the value of echography in the diagnosis of aldosteromas. Tumors were diagnosed at operation in 21 (2 malignant tumors) and adrenal hyperplasia in 2. The accuracy of diagnosis with regard to the presence or absence of aldosteromas was 82.6%. An analysis of the causes of erroneous results showed that they were noted in small size formations less than 2 cm in diameter, in corpulent patients and in the left-side tumor site due to more complicated anatomotopographic interrelationships of the organs in this area.
