CT detection of intrapelvic origin of lower extremity infections in traumatized limbs

Late appearing, lower extremity infections in previously traumatized limbs may originate from occult intrapelvic sources. Computerized tomography can accurately document the intrapelvic source and trace its pathway into the lower extremity. In this paper, we describe two cases of thigh infections originating from pelvic abscesses in limbs that were previously operated on following trauma. Computerized tomography was instrumental in making the diagnosis and directing the appropriate surgical treatment.
