title: Inflammatory pseudotumor of the sigmoid colon mesentery: US and CT findings (2004:12b).
abstract: The concept of inflammatory pseudotumor has evolved from meticulous pathological studies; some of its histological features resemble a spindle-cell sarcoma. Despite the fact that it usually affects children and young adults, only limited numbers of childhood cases have been reported in the pediatric literature. Recognition of this rare entity is important because the clinical manifestations and radiological features may be indistinguishable from a malignant lymphoproliferative disorder. This entity has been reported to be anywhere in the body, including a variety of intra-abdominal organs. Although one of the most common intra-abdominal sites is the mesentery, localization within the mesentery of the sigmoid colon is particularly rare. We present a case of abdominal inflammatory pseudotumor of the sigmoid colon mesentery, defining its radiological and primarily ultrasound and Doppler ultrasound findings, with a review of additional examples from the literature.
