Snapshot in surgery: intraperitoneal encapsulated fat necrosis.

Oh HB, Arab N, Teo L, Lieske B - Clin Case Rep (2014)

Bottom Line: 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.

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.

Mentions: He subsequently underwent a laparoscopic anterior resection and a free-floating white mass was found in the left rectovesical pouch (Fig.1). Histology revealed necrotic adipose tissue with focal calcification, surrounded by a thick dense fibrous capsule with no evidence of malignancy, confirming an encapsulated fat necrosis.
