Organizing Hematoma of the Thigh Multiple Imaging Techniques

Abstract

A chronic, organizing hematoma of the thigh was imaged by multiple techniques. A remote history of trauma was noncontributory. The lesion was located by radiographs. Nuclear medicine studies showed no increased blood supply to the lesion but indicated that it was calcifying and did extend proximally. Ultrasound and CT studies could be variously interpreted to represent either a solid- or a fluid-filled lesion. An angiogram added little useful information. A differential diagnosis of an unexplained traumatic lesion vs a soft tissue tumor was made and surgery was performed. An organizing hematoma was excised.
