title: [Application of echography to the diagnosis of chromaffinomas of extra-adrenal localization].
abstract: 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.
