Enteric duplication cysts are rare congenital malformation, of these, only 4% are gastric origin. It is diagnosed in 80 % of the patients before 2 years of age. Recently, prenatal diagnostic ratio gets higher through sonography and several diagnostic methods. In this paper, we describe a case of a cystic gastric duplication diagnosed prenatally with brief reviews of literature.
Alimentary tract duplications are rare congenital malformations with few reports of the antenatal sonographic appearance. Early diagnosis is of paramount importance to prevent complications. We present a case of a cystic gastric duplication diagnosed antenatally at 31 weeks' gestation, which was treated successfully. Simultaneously, we review all published cases of prenatally diagnosed enteric duplications.
Technetium-99m ((99m)Tc) pertechnetate scintigraphy in a child with acute gastrointestinal bleeding of unknown origin suggests ectopic gastric mucosa caused by Meckel's diverticulum or gastrointestinal duplication cysts. Our objective was to define the patterns of scintigraphic findings likely to be encountered in patients with ectopic gastric mucosa with illustrative cases and to review the literature. Fifty children (age 1 year to 14 years) were evaluated for ectopic gastric mucosa using (99m)Tc pertechnetate scintigraphy. Functioning ectopic gastric mucosa was detected in eight patients with Meckel's diverticula and three patients with bowel duplication. Three patients showed atypical findings on scintigraphy which were perforated appendix, calyceal stasis, and regional enteritis. Ectopic functioning gastric mucosa in Meckel's diverticulum is visualized simultaneously with the stomach, whereas in intestinal duplications tracer activity can be visualized in the dynamic sequence or before gastric tracer visualization in an irregular pattern. A variety of scintigraphic patterns can be found in patients with ectopic gastric mucosa undergoing (99m)Tc pertechnetate scintigraphy depending on the location and size of the ectopic tissue. Also, acquisition of delayed images is useful when the initial images are equivocal in children.
An intraluminal pyloric duplication cyst is an extremely rare congenital anomaly. We report a case of an intraluminal pyloric duplication cyst in a 2-year-old girl with progressive increased vomiting. The patient had an ultrasonography, upper gastrointestinal series, and multiplanar reformatted computer tomography of the abdomen. The diagnosis was confirmed by surgery and histopathologic examination. The patient was asymptomatic at the 12-month follow-up.
The prenatal diagnosis of numerous congenital anomalies has become routine. The prenatal diagnosis of cystic lesions of the retroperitoneum can be due to a variety of renal, gastrointestinal, or adrenal lesions. This finding demands aggressive postnatal follow-up to rule out the possibility of cystic adrenal neuroblastoma. We report the first cases of retroperitoneal cystic masses diagnosed in utero that ultimately proved to be enteric duplications. Therefore, the differential diagnosis of cystic masses of the retroperitoneum found prenatally should be expanded to include enteric duplication cysts.
A newborn baby presented with a lump in the right hypochondrium. She had a bout of upper gastrointestinal bleeding. At operation, a pyloroduedenal duplication cyst was successfully removed. The relevant literature is reviewed.
The first description of the antenatal appearance of a duplication cyst of the pylorus is presented. Prior to the infant's delivery, the possibility that this intra-abdominal cystic mass represented a choledochal cyst was also strongly considered. The antenatal detection of this cystic mass allowed close neonatal surveillance and timely surgical intervention prior to the onset of serious neonatal complications. The embryogenesis of duplication cysts of the gastrointestinal tract and bronchopulmonary foregut malformations is reviewed. The clinical utility of the prenatal diagnosis of such fetal gastrointestinal anomalies is also discussed.
Pyloroduodenal duplication cysts are an extremely rare congenital anomaly, whose clinical signs and symptoms often mimic those of hypertrophic pyloric stenosis. This radiographic analysis revealed configurational changes consistent with a large extrinsic mass rather than muscular hypertrophy, thus leading to the correct preoperative diagnosis.
In this case report a patient is presented, showing large sonolucent areas inside the fetal abdomen at 20 wk of gestation. Gastrointestinal (GI) tract obstruction was suspected. There was no polyhydramnios. After premature delivery the child showed marked abdominal distention, but stayed in good condition without signs of GI tract obstruction. At laparotomy, a 30 cm long, distended duplication of the terminal ileum was removed. Postoperative course was uneventful.
