Although diaphragmatic hernia (DH) may be congenital, posttraumatic, or iatrogenic, DHs after diaphragmatic surgery are rarely reported in the literature. This report describes the rare case of a 14-year-old girl complicated by iatrogenic DH following the biopsy of granulomatous lesions of the left diaphragm, when a mediastinal mixed germ cell tumor was extirpated. Plain computed tomography (CT) with swallowing of GastrografinTM was useful for the diagnosis of this disorder. The patient presented to our hospital with frequent epigastric pain and vomiting 11 months after the original surgery. Chest X-ray, a gastrointestinal contrast study, and plain CT with swallowing of GastrografinTM revealed the left DH with gastric content. At laparotomy, the diaphragmatic defect, 3 × 3 cm in diameter, was repaired using nonabsorbable sutures after hernia reduction. The patient showed a rapid recovery with complete resolution of symptoms. We should consider the presence of iatrogenic DH in patients who develop epigastralgia after procedures involving the diaphragm, even at 11 months after the original surgery. Furthermore, plain CT with swallowing of GastrografinTM is useful for the diagnosis of this disorder.
