HERRANZ BARBERO, Ana et al. Intestinal cystic duplication: Case report. Arch. argent. pediatr. [online]. 2017, vol.115, n.4, pp.e233-e236. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2017.e233.

Intestinal cystic duplications are rare congenital anomalies, with an estimated incidence of approximately 1:4500 autopsies. The etiopathogenesis is uncertain. These duplications are cystic, tubular or diverticular structures lined with gastrointestinal mucosa. They share a common smooth muscle wall with the gastrointestinal tract but usually their lumens do not communicate with each other. Gastric duplication cysts represent 7-9% of the gastrointestinal tract duplication. They can be diagnosed prenatally by fetal ultrasound; magnetic resonance imaging characterizes the cyst and excludes other malformations. Postnatal ultrasound shows a characteristic double walled cyst. Newborns are usually asymptomatic, although nonspecific gastrointestinal symptoms, intestinal obstruction due to mass effect, volvulus or infection are described. In asymptomatic patients, clinical follow-up and periodic image controls are recommended. Elective surgical resection is the treatment of choice, using minimally invasive technique whenever possible. A case of prenatally suspected intestinal cystic duplication is presented.
