case_images: Preoperative ultrasound and chest computed tomography (CT) imaging findings. (A) The chest CT coronal image showed right diaphragmatic elevation, suspected an abnormal mass herniated into the chest cavity. (B) Chest ultrasound confirmed that the right kidney had herniated into the right chest cavity. (C) Contrast enhanced chest CT scan showed that the rotation position of the right kidney was significantly shifted upwards above the diaphragm (coronal position). (D) The local discontinuity in the right diaphragm (sagittal position). (E) Thickening of the upper wall of the hernia sac with significant enhancement on enhanced scanning. (F) The abnormal supply of small blood vessel originating from the right renal artery. ( : Right kidney,  : Hernia sac,  : Left kidney,  : Diaphragmatic muscle,  : Infradiaphragmatic pulmonary sequestration,  : Abnormal blood vessels,  : Right kidney artery,  : Right kidney vein).

case_images: CDH (Figure 1A). Chest ultrasonography confirmed that the right kidney had herniated into the right chest cavity (Figure 1B). Small blood vessels from the renal artery branch were observed running inside, suggesting infradiaphragmatic pulmonary sequestration and ITK associated with CDH (Figures 1C-F).

case_images: Intrathoracic endoscopic images. (A) The right kidney had herniated into the chest cavity on the posterior lateral side of the diaphragm, which was placed back into the abdominal cavity. The hernia sac was thin. (B) Upon incision of the hernia sac, a bright red colored lesion with clear boundaries was observed. (C) Visible a small abnormal blood vessels supplying the lesion. (D) The repair of diaphragmatic hernia was smooth. ( : Hernia sac,  : Infradiaphragmatic pulmonary sequestration,  : Abnormal blood vessels).

case_images: The hernial sac was thin (Figure 2A). Upon incision of the hernia sac, a bright red lesion with clear boundaries and an abnormal blood vessel supply was observed (Figures 2B,C). After cutting off the abnormal blood vessels, LigaSure TM was used to remove the diseased tissue, and the renal fat sacs and renal tissue were visible (Figure 2D).

case_images: Follow up chest computed tomography (CT) imaging and renal ultrasound findings at 2 months post-surgery. (A) The chest CT coronal image showed that right diaphragm was in the normal position. (B) The chest CT coronal image showed that right kidney had returned to the abdominal cavity. (C) The renal ultrasound showed that blood flows in the right renal artery and vein were smooth. ( : Right kidney artery,  : Right kidney vein).

case_images: Two months after surgery, chest CT showed that the right kidney had returned to the abdominal cavity and the right diaphragm was in a normal position, renal ultrasound showed that blood flow in the right renal artery and vein were smooth (Figure 3).
