“…In cases of huge intra-and retroperitoneal mass with or without seeding, neuroblastoma, germ-cell tumour, Wilms' tumour [12], desmoid tumour, and Ewing's sarcoma/PNET may be included in the differential diagnosis. For diffuse intraperitoneal nodules or masses, the differential diagnosis may include a broad spectrum of tumours, including peritoneal lymphomatosis [13], peritoneal sarcomatosis [14], peritoneal carcinomatosis, intraperitoneal rhabdomyosarcoma [15], peritoneal mesothelioma, and even secondary seeding of intracranial tumours by ventriculoperitoneal shunts [16].…”

Intra-abdominal desmoplastic small round-cell tumour: multiphase CT findings in two children

2003

We report the multiphase CT findings of intra-abdominal desmoplastic small round-cell tumour (DSRCT) in two children. CT showed a huge heterogeneous intraperitoneal mass with or without direct invasion into solid organs such as liver or kidney, extensive intraperitoneal seeding, intratumoural calcification, ascites, and lymphadenopathy. DSRCT should be included in the differential diagnosis of malignant intraperitoneal neoplasm in children. Multiphase CT may be helpful in delineating tumour extent, vascularity and direct invasion into adjacent organs.

“…Rhabdomyosarcoma can arise in or metastasize to almost any site, but the head and neck and the genitourinary tract are the most common sites of origin (123). Approximately 10% of patients have intraperitoneal involvement (125), which may represent metastatic or primary de novo disease (125)(126)(127)(128).…”

Intraperitoneal solid tumors are far less common in children than in adults, and the histologic spectrum of neoplasms of the peritoneum and its specialized folds in young patients differs from that in older patients. Localized masses may be caused by inflammatory myofibroblastic tumor, Castleman disease, mesenteric fibromatosis, or other mesenchymal masses. Inflammatory myofibroblastic tumor is a mesenchymal tumor of borderline biologic potential that appears as a solitary circumscribed mass, possibly with central calcification. Castleman disease is an idiopathic lymphoproliferative disorder that appears as a circumscribed, intensely enhancing mass in the mesentery. Mesenteric fibromatosis, or intra-abdominal desmoid tumor, is a benign tumor of mesenchymal origin associated with familial adenomatous polyposis. Mesenteric fibromatosis appears as a mildly enhancing, circumscribed solitary mass without metastases. Diffuse peritoneal disease may be due to desmoplastic small round cell tumor (DSRCT), non-Hodgkin lymphoma, or rhabdomyosarcoma. DSRCT is a rare member of the small round blue cell tumor family that causes diffuse peritoneal masses without a visible primary tumor. A dominant mass is typically found in the retrovesical space. Burkitt lymphoma is a pediatric tumor that manifests with extensive disease because of its short doubling time. The bowel and adjacent mesentery are commonly involved. Rhabdomyosarcoma may arise as a primary tumor of the omentum or may spread from a primary tumor in the bladder, prostate, or scrotum. Knowledge of this spectrum of disease allows the radiologist to provide an appropriate differential diagnosis and suggest proper patient management.

“…1 There is only one case series of intraperitoneal RMS in children in the literature, which found an incidence of 11% (6/55) over the course of the disease, and of 7% (4/55) at the time of initial diagnosis. 2,3 This, however, included both primary and metastatic disease (only one case with peritoneal spread without a determined primary). Chung et al 3 the most common imaging finding in peritoneal RMS is ascites, intraperitoneal nodules and masses and mesenteric nodules.…”

“…To date, only five cases of RMS in mesenteric location have been reported in the literature, only one of which was in a child. 5e8 There are no references for the radiologic findings of mesenteric RMS, however Chung et al 2 , Leung et al 3 and Oto et al 4 described the imaging characteristics of intraperitoneal and omental rhambdomyosarcoma.…”
