title: Contrast-enhanced sonographic appearance of malignant fibrous histiocytoma in the sigmoid colon: a case report.
abstract: Malignant fibrous histiocytoma (MFH) of the sigmoid colon is extremely rare and imaging characteristics of MFH during contrast-enhanced sonography have not been described yet. Here we report the case of a 55-year-old man suffering from MFH in the sigmoid colon, with an emphasis on contrast-enhanced sonography findings.
