Gastric Bronchogenic Cyst Histologically Diagnosed After Laparoscopic Excision: Report of a Case

Abstract

Abdominal computed tomography of a 71-year-old man revealed a 3-cm mass in gastric cardia. Although the mass was widely attached to the gastric wall, no clear contrast enhancement was observed. Abdominal magnetic resonance imaging revealed the mass to have homogenous high intensity on T2W1 images and isointensity on T1W1 images. On diffusion-weighted imaging, no high intensity was observed. However, the mass had a smooth surface and was widely attached to the gastric wall, consistent with computed tomography findings. A gastric submucosal tumor was suspected. Laparoscopic tumor resection was performed. Histopathologic diagnosis of the mass was a bronchogenic cyst derived from the respiratory primordium originating in the foregut of the primitive intestine. Such cysts are mostly found in the mediastinum or thoracic cavity; their occurrence on the gastric wall is extremely rare. Despite this, we think that bronchogenic cysts should be considered in the differential diagnosis of abdominal unilocular cystic diseases.

Lipoma-Like Bronchogenic Cyst in the Right Chest Sidewall: A Case Report and Literature Review

“…5) In addition, bronchogenic cysts can occur in the lungs, esophagus, stomach wall, paravertebral gutter, skin and subcutaneous area. 6) The cysts can also move to atypical sites including neck, myocardium, pericardium, thymus, lung ligament, diaphragmatic and retroperitoneal region, and abdomen. 2,4,7,8) Sometime, the cysts may even exhibit a dumbbell shape, with one part being located above the diaphragm and the other part being located below the diaphragm.…”

Sub-Diaphragmatic Bronchogenic Cysts: Report of Two Cases

“…Some authors also describe the gastric duplication cysts in the foregut as cystic malformations. Cartilage and glandular tissue is present on the wall of bronchogenic cysts; however, gastric duplication cysts are lined with gastric mucosa [2,4,7]. In both of our cases, the cyst was lined with respiratory epithelium and smooth muscle tissue and sero-mucinous acini were present on the cyst wall.…”

“…Endoscopic ultrasound or fine needle aspiration do not give exact results every time. Moreover, aspiration-associated complications such as fistula formation and bleeding have been reported in the literature [5][6][7][8]. For that reason, exact diagnosis is made with the histopathological evaluation of resection material, as in our cases.…”

“…For that reason, in asymptomatic cases, surgery is controversial. However, since preoperative diagnosis is difficult and there are some complications due to percutaneous or endoscopic aspirations, surgery may be an option for both diagnosis and treatment [2,4,7,8].…”

Bronchogenic cyst arising from the crus of the left hemidiaphragm

“…In most cases, the cysts are associated with the tracheobronchial tree (although lacking continuity)2 and are most commonly found in the posterior carina, however, they may also be found in atypical locations, such as intraspinal,3 subdiaphragmatic or retroperitoneal regions 1. To date, there have been 48 cases of subdiaphragmatic bronchogenic cysts described in the English literature, with retroperitoneal location being very rare 4.…”
