Organo‐axial volvulus of the sigmoid colon

Abstract

A 59 year old man presented with subacute abdominal distension and diarrhea. Plain radiographs and barium enema demonstrated organo-axial volvulus of the sigmoid colon. The radiologic, surgical, and pathologic findings are presented. The radiologic differences between organo-axial volvulus and the common mesentero-axial volvulus of the sigmoid colon are discussed.
