title: Computed tomography of lower extremity tumors.
abstract: Fifty cases of lower extremity tumors examined with computed tomography were reviewed. Of the 50 cases, 41 had gross pathologic correlation, either by enbloc resection (26) or by amputation (15). Important information regarding size, location, definition, and anatomic relation of tumors to vital structures (neural, vascular, and osseous) may be ascertained by this means with great accuracy. Localization of vessels by intravenous infusion of contrast material during the scan, or after arteriography with intraarterial contrast infusion, is found to enhance such evaluation. This information is particularly important where the feasibility of en-bloc resection is being evaluated.
