She is symptoms free between theses episodes. The upper digestive endoscopy showed an aspect suggestive of submucosal lesion or extrinsic compression in the second portion of the duodenum. The abdominal CT Scan showed am anomalous right kidney with marked mobility dilation of the secretory tree that was the cause of duodenal compression. After urological surgery (pieloplasty and kidney fixation) the patient was followed during two years without any symptoms.porExtrinsic compression of the duodenumanomalous kidneyjournal article
