His history included that he had 2 angiographically detected aberrant pulmonary arteries extending from the descending aorta to the right and left lungs, respectively. Both collaterals had been ligated during the corrective surgery; however, early postoperative evaluation revealed that the vessel that crossed behind the esophagus to the left lung had become recanalized. Coil embolization was performed to occlude this collateral. The patient had begun to develop swallowing difficulties 2 years after the embolization. Esophagography revealed a significant stricture in the middle of the esophagus, just anterior to the location of the coil in the vessel behind. The patient underwent a program of esophageal dilatation. This was successful, and he regained normal swallowing ability. To our knowledge, no similar case of esophageal stenosis has been reported in the English literature. We believe that inflammation surrounding the coiled aberrant artery, presumably caused by injury during the corrective surgery and resulting in hemorrhage, led to fibrosis around the vessel. This fibrosis also involved the adjacent esophageal wall, thus causing progressive stenosis.展开更多

Less than 2%of cases occur in childhood, relatively in older age group. Only a few pediatric series have been presented in the English literature. Tumor is presented with characteristic findings of flank pain, gross hematuria, and palpable mass. Although one half of the patients have metastasis at the time of diagnosis, most cases are currently being incidentally detected using improved imaging techniques. The overall prognosis in children appears to be similar to that in adults. Tumor stage and complete surgical resection have been reported as the most meaningful prognostic factors for the outcome. The incidence of metastatic disease is same as in adults. The effect of chemotherapy and immunotherapy, either preoperatively or postoperatively, is unclear. Cure is the most likely consequence in localized and completely resected tumors. Here, we present an 8-year-old boy with renal cell carcinoma demonstrating only hematuria without any pathological physical examination findings. The mass was described by abdominal ultrasonography and computed tomography in the left kidney. After the left nephroureterectomy, the patient was given no therapy.展开更多
