Computed tomography of ilio-psoas muscle tumors.
A retrospective evaluation of computed tomographic scans done at our institution showing psoas muscle tumors is presented. The anatomy of the psoas muscle along with a discussion of normal psoas anatomy which can be mistaken for tumor are reviewed. Primary muscle tumors along with metastatic, neurogenic, and lymphomatous tumors affecting the psoas muscle is discussed. The use of computed tomography for assessment of extent, origin, and structure of psoas muscle tumors is demonstrated.
