Introduction:
To date, multiple variations in the pelvic vasculature have been reported. In this case report, a rare, so far unreported, branching anomaly of the internal iliac artery on the left side of a male human pelvis is described.
Report:
The complete posterior division of the internal iliac artery was shown to be missing on dissection of a 73 year old male cadaver. The iliolumbar artery, the lateral sacral arteries, and the superior gluteal artery originated unilaterally (on the left pelvis) directly from the common iliac artery.
Discussion:
No alteration was observed in the supplied structures of the left pelvic region, including the respective muscles, the sacrum, or the hip joint.
