Human anatomic variations: common, external iliac, origin of the obturator, inferior epigastric and medial circumflex femoral arteries, and deep femoral artery course on the medial side of the femoral vessels.

Probably, the most variable anatomic pattern relates to the iliac arteries system. There are reported here multiple rare anatomic variants found in a single case, at CT evaluation: (a) the unilaterally present common trunk of origin of the obturator, inferior epigastric, and medial circumflex femoral arteries and (b) the medial insertion of the deep femoral artery (DFA) onto the femoral artery, which placed the DFA initially on the medial side of the femoral vein. Such rare, but possible, anatomic variations should recommend surgeons to plan the procedures on a case-by-case basis.
