Desmoplastic small round cell tumour in the Afro-Caribbean population: case report with imaging findings

Desmoplastic Small Round Cell Tumour (DSRCT) is a rare malignancy that has only a few cases documented in the literature. We report a case of DSRCT in the abdomen and pelvis that was identified following ultrasound-guided biopsy of one of the numerous liver lesions seen on imaging in a 13-year-old Afro-Caribbean female with increased abdominal girth. The tumour was characterized by all routine imaging modalities available at the time. To our knowledge, this is the first reported and published case in the English speaking Caribbean. In the review of the literature, we correlate the imaging findings with previously reported cases. The diagnosis of DSRCT cannot be made solely using standard imaging techniques, but radiologists should be suspicious of DSRCT as a differential diagnosis in a young patient with increased abdominal girth, multiple liver and peritoneal deposits seen on imaging. Written informed consent for the case to be published (incl. images, case history, and data) was obtained from the parents of this patient for publication of this case report, including accompanying images.
