Comparison of the unusual vessel ramifications resulting from the missing posterior division of the internal iliac artery (A and B) on the left pelvic side and the usual vessel branches of the internal iliac artery (C and D) on the right pelvic side. AD = anterior division; CIA = common iliac artery; EIA = external iliac artery; IIA = internal iliac artery; ILA = iliolumbar artery; LSA = lateral sacral arteries; PD = posterior division; SGL = superior gluteal artery.

The photographic documentation was followed by the coloring of distinctive structures: red for arteries, blue for veins, and yellow for nerves (Fig. 1). SGL originated from the CIA (Fig. 1A and B). Such an anomaly of these blood vessels has not been described previously in the literature.
