Corkscrew sign of midgut volvulus

  • Corkscrew sign - describes the spiral appearance of the distal duodenum and proximal jejunum in the setting of midgut volvulus on contrast studies. In patients with congenital malrotation of the midgut, the distal duodenum and proximal jejunum do not cross the midline and instead pass inferiorly. These loops are predisposed to twist on their shortened mesentery creating the classic corkscrew appearance of midgut volvulus.
