Pyloric adenomyoma: a rare cause of gastric outlet obstruction in childhood

“…It is composed of two layered muscularis propria with variable gastrointestinal mucosal lining. 8 Brunner's gland heterotopia is another differential diagnosis frequently found in the prepyloric region. 6 It consists of diffuse or nodular Brunner's glands without smooth muscle bundles, occupying the submucosal layer.…”

Pyloric Duplication: About Two Cases

“…Ultrasound is the most common modality. It may reveal the inner hyperechoic and outer hypoechoic layers (double-wall sign) that are typical of duplication cysts considered by Deftereos as a confirmation of the diagnosis [4,24]. However, in the case we described, ultrasound showed, only, an anechoic cystic mass with a single hyperechoic wall, and the typical double-wall sign was not reached.…”

“…Nuclear scans using radioisotopes may show tracer uptake by ectopic gastric mucosa. Magnetic resonance imaging studies are useful in demonstrating the relationship with other structures [4,15]. If, after appropriate investigations, the diagnosis remains unclear, we suggest that laparoscopy should be used to confirm the diagnosis [22].…”

“…Some GID may be totally asymptomatic, identified on routine physical examination or during investigations for other problems. Common clinical manifestations of pyloric duplications include a palpable abdominal mass and non bilious vomiting which is almost present in all the cases of literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Bleeding, intussusception can be an occasion for discovering such unusual anomalies [3,20].…”

“…In most cases preoperative diagnosis is not made [2]. To our knowledge, no more than 20 cases of pyloric duplication have been reported in the English literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], most of them were extra luminal masses. Here in, we describe two cases with pyloric duplication cyst.…”
