Gastric duplication cyst: case report

Thoracoabdominal duplication cyst: US, CT and MR findings

“…Infants and children usually present with high-level GI obstruction, whereas older age groups occasionally present later, with unusual symptoms which include anaemia, relapsing pancreatitis [11], haematemesis and melena [12], ulceration [13], torsion, perforation, infection and neoplastic transformations [2,8]. Because our case did not contain ectopic gastric mucosa, the haematemesis was most likely secondary to pressure necrosis produced by its extrinsic mass effect on the stomach.…”

“…Gastric duplications are in most cases (85 %) noncommunicating and spherical structure, or tubular structure (15 %), which communicate with the organ located adjacent to it [2][3][4]. Ectopic tissues can be found in the walls of these lesions at all levels of duplications [3,4,9].…”

“…Radiology plays a decisive role in the diagnosis [2]. Plain radiographs have a limited role, other than demonstrating the masses associated with thoracic vertebral anomalies [3].…”

“…Duplication of the gastrointestinal tract (GI) is a rare congenital anomaly which can occur in any segment of the alimentary tract [1][2][3][4]. By definition, they are located in or adjacent to the wall of the GI, have smoothmuscle tissue in their walls and are lined by alimentary tract mucosa [3].…”

“…By definition, they are located in or adjacent to the wall of the GI, have smoothmuscle tissue in their walls and are lined by alimentary tract mucosa [3]. Morphologically, they may be spherical or tubular; may or may not communicate with the organ of origin to whose mesenteric fold they are closely connected [2][3][4]. Thoracoabdominal GI duplications are a rare, but distinct, variety of tubular duplications which arise in the abdomen, pass through the diaphragm and can produce symptoms secondary to its mass effect in the posterior mediastinum [3][4][5][6].…”
