title: [Magnetic resonance imaging of non-organic bulky masses of the retroperitoneal space. Part 2. Primary and metastatic tumors].
abstract: Based on MRI findings in 15 patients with primary non-organic tumors and 9 patients with metastatic neoplasms of the retroperitoneal space, the paper describes the MRI-semiotics of these diseases and proposes methodological approaches to their identification in its second part. By comparing the data of MRI and autopsies, the author defines the values of the sensitivity, specificity, and accuracy of the technique in detecting primary and metastatic non-organic tumors of the retroperitoneal space. The author emphasizes the advantages and disadvantages of MRI, shows how difficult to make a differential diagnosis of benign and malignant types of primary non-organic tumors by means of this method.
