儿童腹腔内实性肿瘤
Intraperitoneal Solid Tumors in Children
儿童局灶性肠系膜肿物：
- 炎性肌纤维母细胞瘤（IMT）
- Castleman病
- 肠系膜纤维瘤病
左上图：典型的炎性肌纤维母细胞瘤，表现为单发的边界清楚的病变，中心可见粗糙的钙化。
儿童弥漫性腹膜病变：
- 促结缔组织增生性小圆细胞肿瘤（DSRCT）
- 非霍奇金淋巴瘤
- 横纹肌肉瘤
右下图：DSRCT，表现为腹盆腔巨大肿瘤，压迫膀胱，常合并腹水及多发腹膜种植。
A focal mesenteric mass in a child may be an inflammatory myofibroblastic tumor, Castleman disease, or mesenteric fibromatosis. A typical inflammatory myofibroblastic tumor (upper left) is shown as a single well-circumscribed lesion with coarse central calcifications. Diffuse peritoneal disease may be a desmoplastic small round cell tumor (DSRCT), non-Hodgkin lymphoma, or rhabdomyoscarcoma. A DSRCT (lower right) usually manifests as a large abdominal or pelvic tumor (shown here depressing the bladder), often accompanied by ascites and multiple peritoneal implants.
