Abstract:
Objective To investigate the CT features of desmoplastic small round cell tumor (DSRCT)occurred in abdomen and pelvis.Methods The CT images of 4 patients with pathologically proven DSRCT occurred in abdomen and pelvis were retrospectively analyzed.Results The CT features common to the 4 DSRCT in abdomen and pelvis were as follows:the lobulated soft-tissue masses were very large;the masses often involved omental and serosal surfaces of abdomen and pelvis organ and had close relationship to the surrounding organs;the originating site of the tumors were not apparent;intratumoral hemorrhage or necrosis were often present;and contrast-enhanced CT scan showed mild to medium heterogeneous enhancement.Conclusion The CT features of DSRCT in abdomen and pelvis are rather specific and can provide helpful information to the clinical diagnosis.
