Desmoplastic Small Round Cell Tumor in the Abdomen and Pelvis: Report of CT Findings in 11 Affected Children and Young Adults

Abstract

Characteristic CT features of DSRCT include bulky intraabdominal soft-tissue masses that involve omental and serosal surfaces, without a distinct organ of origin; solid, dominant, heterogeneous pelvic masses in the retrovesical or rectouterine spaces; and concurrent metastases, common at the time of diagnosis, particularly those involving lymph nodes and liver.
