Iliac colon

The iliac colon is situated in the left iliac fossa, and is about 12 to 15 cm. long.

It begins at the level of the iliac crest, where it is continuous with the descending colon, and ends in the sigmoid colon at the superior aperture of the lesser pelvis.

It curves downward and medialward in front of the Iliacus and Psoas, and, as a rule, is covered by peritoneum on its sides and anterior surface only.
