[Computer tomography in the diagnosis of retroperitoneal nonorganic tumors]

The results of a follow-up of 128 patients with retroperitoneal nonorganic tumors showed that among diagnostic methods computerized tomography (CT) proved to be a valuable method in the recognition of nonorganic tumors of the retroperitoneal space permitting one to detect neoplasms in 92.6%. In spite of the fact that the main bulk of retroperitoneal nonorganic tumors had various images on computerized tomograms this method provided an opportunity to judge of the nature of nonorganic neoplasms on the basis of correlation of their structural elements, the prevalence of this or that tissue and the expression of disintegration processes. Diagnostic errors in CT of the patients with retroperitoneal nonorganic tumors were associated with objective difficulties determined by the peculiarities of interrelationships of a growing tumor with the adjacent organs.
