"Spoke wheel" sign of small intestinal volvulus

Radiographic diagnosis of small intestinal volvulus and gangrenous change produced by an adhesive band is presented. A soft-tissue mass with radiating mucosal folds simulating a "spoke wheel" was found in the right mid-abdomen. Expansion of the mass was documented on a follow-up radiograph 3 hours later. A "spoke wheel" sign is reported as an early indication of small intestinal volvulus.
