title: Snapshot in surgery: intraperitoneal encapsulated fat necrosis.
abstract: A 66-year-old man with rectal cancer was found to have an incidental ring-like lesion in the left rectovesical pouch. Histology revealed an encapsulated fat necrosis. Intraperitoneal encapsulated fat necroses are postulated to be a result of infarcted epiploic appendages resulting in a free-floating lesion.
