Sonographic Detection of Fibromatosis

Abstract

Abdominal sonography for the detection and evaluation of mass lesions is a common investigative modality. The authors wish to report a case of an unusual retroperitoneal tumor that was detected by ultrasound. The lesion, fibromato sis, was symptomatic but went undiagnosed for over a year, despite two evalua tions which included multiple standard roentgenographic studies. Fibromato sis is discussed.
