During routine dissection, we found variations in the branches of Internal Iliac Artery (IIA) of a 65-year-old Iranian female cadaver. The IIA ended by dividing to an unusual smaller anterior and a greater posterior trunk which was branched to the inferior gluteal arteries. Both pelvis and the uterine artery were separated from the umbilical artery in the left side. In addition, the left iliolumbar artery arose from the main trunk of IIA. Although this cadaver had some uncommon variations, the findings are significant from clinical perspective.</p> Internal iliac artery, Inferior gluteal artery, Iliolumbar artery, Arterial variation 57 60 http://anatomyjournal.ir/browse.php?a_code=A-10-133-1&slc_lang=en&sid=1 Yousef Mohamadi yosef.1365@yahoo.com 10031947532846003574 10031947532846003574 No Department of Anatomy, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran.
