Diagnosis and evaluation of retroperitoneal tumors by computed tomography

Nineteen patients with primary and recurrent retroperitoneal tumors were examined by computed tomography. Correlation between CT and subsequent operative findings was remarkably accurate. CT provided clinically useful information regarding the presence, size, extent, and composition of the tumors and also their effect on adjacent structures. CT is recommended for any patient suspected to have a primary or recurrent retroperitoneal tumor.
