Table 1 Cases of gastric adenomyoma in children

Ref.	Gender	Age	Symptoms	Imaging	Preoperative diagnosis	Surgery
Moiseenko[9], 1964	Female	5 months old	Esophageal reflux	Barium swallow indicated esophageal reflux	Esophageal reflux	Nissen fundoplication and mass excision
Takeyama et al[16], 2007	Female	1 month old	Intermittent vomiting free of bile of one week	US demonstrated heterogeneous intramural mass of the pyloric region	Hypertrophic pyloric stenosis	Lesion excision
Min et al[2], 2012	Female	5 years old	Intermittent epigastric pain, vomiting, poor oral intake, irritability, and fever	US and CT demonstrated a thick-walled cystic lesion; UGI showed an extrinsic mass with a lobulated contour without evidence of perforation	Gastric duplication cyst	Distal gastrectomy with gastroduodenostomy
Castain and Rullier[10], 2012	Female	4 months old	Vomiting, weight loss, and abdominal pain	US showed a non-circumscribed heterogeneous mass of the pyloric wall with microcystic features	Hypertrophic pyloric stenosis	Pyloric junction removal
Rhim et al[17], 2013	Male	1 week old	Persistent vomiting	US showed asymmetrical submucosal thickening of the anterior wall of the pylorus and the lesion protruded into both luminal and serosal sides; UGI showed elongation and narrowing of the pyloric canal and shouldering of the antrum	Gastric outlet obstruction	Billroth I anastomosis
Aljahdali et al[11], 2012	Male	13 days old	Progressive nonbilious vomiting	US demonstrated a hyperechoic intramural pyloric mass	Pyloric stenosis	Mass dissection and Graham patch repair
Oviedo Gutiérrez et al[19], 2015	Female	49 days old	Nonbilious vomiting of 48 hours	US showed a nonobstructive nodular lesion in the anterior pyloric wall; MRI suggested a myofibroblastic tumor	Hypertrophic pyloric stenosis	Complete resection of the pyloric tumor
Arslan et al[20], 2018	Female	5 years old	Abdominal pain, poor oral intake, and fever	US showed an intramural hypoechoic heterogeneous nodular mass; CT revealed a cystic lesion	Gastric duplication cyst	Mass excision, double-layer transverse anastomosis
Kamrani et al[18], 2019	Female	15 years old	Nausea and vomiting over a period of two years	CT showed a circumferential prepyloric mass; EGD showed the distal antrum and proximal pylorus contained a frond-like circumferential nearly obstructing submucosal mass	Gastric duplication cyst	Distal gastrectomy with gastroduodenostomy

US: Ultrasound; CT: Computed tomography; UGI: Upper gastrointestinal series; MRI: Magnetic resonance imaging; EGD: Esophagogastroduodenoscopy.
