Value of ultrasonography in the detection of retroperitoneal inflammatory masses.

The ultrasonographic and radiologic findings for 7 patients with retroperitoneal inflammatory processes are presented. Ultrasonographic findings were critical to the diagnosis in 6 of the 7 patients and allowed for rapid evaluation and the institution of successful therapy. The relative sensitivity and specificity of ultrasonography is compared with conventional radiologic modalities. The application of diagnostic ultrasound to the problem of retroperitoneal inflammation is advocated.
