Fibrosing mesenteritis simulating pelvic carcinomatosis

Abstract

A case of fibro-inflammatory thickening of the mesosigmoid simulating pelvic carcinomatosis on barium enema and ultrasound examination is presented. Histologic features of this case and cases of retractile mesenteritis and mesenteric panniculitis are discussed.

Sonographic detection of mesenteric panniculitis: Case report and literature review

“…A review of the literature identified only eight cases studied with sonography. 2,[6][7][8][9][10] Sonography may show a well-defined, echodense mass with small, frequently central, hypoechoic areas, 2,6 an irregularly-shaped hypoechoic area, 2 or a heterogeneous but predominantly hyperechoic mass. 9 Small calcifications are frequently identified by pathologists but are rarely recognized in plain films or CT studies.…”

Mesenteric Fibromatosis

“…A diagnosis of fibromatosis is highly likely when lymphocytic infiltration is absent (or at least minimal if there are no foam cells), when the fibroblasts are of uniform size and when there is invasion of adipose tissue and of the muscular layer of the intestinal wall 4 , 5 , 7 , 9 ,. 16 Necrosis in the mesenteric adipose tissue and the presence of numerous foam cells, lymphocytes, plasma cells, haemorrhage, haemosiderin and postnecrotic pseudocysts is strongly in favour of a postinflammatory or post‐traumatic mesenteric fibrosis 17–19 . The differential diagnosis in rare cases includes leiomyoma, leiomyosarcoma, fibrosarcoma, liposarcoma, neurofibroma, fibrous mesothelioma, malignant schwannoma and undifferentiated sarcoma 7 …”
