gas; barium complications; barium swallow examination; prednisolone
Key clinical message: We found an extremely rare case of PVG
after barium swallow examination. This may be related to vulnerable
intestinal mucosa in the patient undergoing prednisolone treatment.
Conservative therapy should be considered for patients with PVG without
bowel ischemia or perforation. Caution should be exercised during barium
examination undergoing prednisolone treatment.
