Obstructive Jaundice Caused by Metastatic Neuroendocrine Tumor of the Ampulla of Vater in a Young Adult: A Case Report

Introduction: Ampullary neuroendocrine tumors (NETs) are usually diagnosed in the 5th–6th decades of life, and no cases were reported in <20 years of age. We report a rare case, presenting at a very young age, of well-differentiated NET involving the ampulla of Vater with lymph node metastasis. Case Presentation: An 18-year-old man presented with a 3-month history of upper abdominal pain and jaundice. Abdominal ultrasound showed a dilated common bile duct, and endoscopic retrograde cholangiopancreatography revealed two duodenal polypoid lesions, one of them overlying the ampulla of Vater, with an erythematous and ulcerated surface. Histopathological examination confirmed the diagnosis of NET grade 1. Octreotide scan revealed 2 para-aortic lymph nodes with intense radiotracer uptake. The patient had undergone Whipple surgery with para-aortic lymph node dissection. Histopathological examination of the surgical specimens was confirmatory of NET grade 2 and paraganglioma in a few of the dissected lymph nodes. Postoperatively, the patient was kept on monthly intramuscular octreotide. Follow-up gallium-68 DOTATATE is unremarkable apart from an avid left para-aortic lymph node which is showing stability over 12 months of follow-up. Conclusion: This case demonstrates that NETs of the ampulla of Vater can present at a very young age. Radical surgical excision with extended lymph node dissection and postoperative octreotide is associated with better patient outcomes and survival

Acquired right-sided diaphragmatic hernia in a patient with retroperitoneal hydatidosis: a case report and review of the literature

Abstract Background Diaphragmatic hernia is primarily congenital in origin and has potentially devastating pulmonary complications. Acquired diaphragmatic hernia as a complication of hydatid disease remains a rare clinical entity. Retroperitoneal hydatidosis, in particular is an exceptionally rare cause behind a similar presentation. This paper aims to present the first case of acquired diaphragmatic hernia likely caused by eroding retroperitoneal hydatid cysts and provide a succinct literature review regarding the causative association between hydatid disease and diaphragmatic defects. Case presentation A 71-year-old Saudi man, with a history of hydatid disease involving several areas including the retroperitoneum, presented with multiple episodes of shortness of breath and abdominal pain of 10 months’ duration. Computed tomography scans of the chest and abdomen demonstrated the presence of a large diaphragmatic defect, with herniation of bowel loops into the chest cavity. Initially, the patient underwent a diagnostic laparoscopy which was then converted to a posterolateral thoracotomy to repair the defect. Conclusions The ability of hydatid disease to involve several body organs makes diagnosis and management of resultant complications a challenge in some cases, like ours. Knowledge about a reported rare complication could enable early detection and management to avoid serious complications, including abdominal viscera incarceration and strangulation
