Volvulus is a benign colonic pathology of the cecum or sigmoid colon.

General

  • Uncommonly comes to pathology.
  • It is essentially a radiologic diagnosis.
  • In the context of autopsy, it is a gross diagnosis.

Gross

  • Intestine folded over itself - typically leads to ischemia.

Radiology

  • In the context sigmoid volvulus - the colon may be described as having a coffee bean sign.[1]
    • The "coffee bean" is: large bowel folded over itself and twisted in away that creates two compartments.[2]

Features:

Sign out

RECTOSIGMOID, RESECTION:
- MURAL ISCHEMIA WITH PERFORATION, SEROSITIS, MICROABSCESS FORMATION AND POORLY FORMED PSEUDOMEMBRANES.
- SUBMUCOSAL FIBROSIS.
- NEGATIVE FOR MALIGNANCY.

COMMENT:
The findings are consistent with volvulus and the submucosal fibrosis suggests this may have been recurrent.
