In the proximal sigmoid colon round, well-circumscribed, homogeneous lesion measuring 47 mm transverse x 43 mm AP x 49 mm craniocaudal. The lesion has homogenous fat density. A short segment, approximately 40 mm in the length, of intussusception is noted directly proximal to the lesion. No evidence of a large bowel obstruction.
Incidental note is made of the hemorrhagic cyst in the right kidney (pre-contrast phase not shown).
Large colonic lipoma in the proximal part of the sigmoid serving as a lead point for a short-segmental colocolic intussusception.
Importantly there are no signs of large bowel obstruction.
