SUPERIOR MEDIASTINAL MASS CAUSING GASTRIC OUTLET OBSTRUCTION

We present a unique case of a 63-year-old male patient with a squamous cell carcinoma of right upper lobe with paratracheal lymphadenopathy and symptoms of superior vena caval obstruction treated by radiotherap y, presented seven months later with symptoms of gastric outlet obstru ction. Upper GI endoscopy and barium studies confirmed the diagnosis o f functional gastric outlet obstruction. He was treated by an antecoli c gastrojejunostomy. We postulate that the superior mediastinal mass w ith vagal nerve entrapment at the thoracic inlet resulted in symptoms of gastric outlet obstruction.
