Predisposing factors for developing gastric volvulus and the role of imaging.

Two cases of gastric volvulus are presented to highlight the predisposing factors, mechanism and different types of volvulus, and the role of imaging in making the diagnosis. Eventration of the diaphragm and hiatus hernia are precipitating factors for developing organo-axial and mesentero-axial volvulus. Imaging is key to making the diagnosis and distinguishing the types of volvulus in order to decide on management.
