Fibromatosis involving pelvic floor muscles.

Fibromatosis or desmoid tumour is a benign fibroblastic proliferation with aggressive infiltrative growth. High incidence of recurrence is noted after incomplete resection of the involved margins of the lesion. Pelvic fibromatosis is a rare condition and usually affects females.

Local staging and assessment of colon cancer with 1.5-T magnetic resonance imaging.

Objective:: The aim of this study was to assess the accuracy of 1.5-T MRI in the pre-operative local T and N staging of colon cancer and identification of extramural vascular invasion (EMVI).

Methods:: Between 2010 and 2012, 60 patients with adenocarcinoma of the colon were prospectively recruited at 2 centres.

Perfusion CT vascular parameters do not correlate with immunohistochemically derived microvessel density count in colorectal tumors.

Purpose: To determine whether perfusion computed tomography (CT)-derived vascular parameters-namely, blood flow, mean transit time (MTT), volume transfer constant (K(trans)), permeability-surface area product (PS), extracellular extravascular space volume, and vascular volume-correlate with the immunohistologic markers of angiogenesis in colorectal tumors.

Materials And Methods: This prospective study was approved by the Regional Ethics and Research and Development Committees. The perfusion CT protocol was incorporated in the staging CT after informed consent in 29 patients (14 men, 15 women; mean age, 70 years; age range, 55-94 years).
