Objective: Our objective was to evaluate the CT features of desmoplastic small round cell tumor (DSRCT) of the abdomen and pelvis in pediatric and young adult patients.
Conclusion: 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.
