Bronchopulmonary sequestration (BPS), a congenital malformation that usually presents as a chest mass in childhood, may be identified by its characteristic primary derivation of pulmonary blood supply from the systemic circulation. Five children with BPS were evaluated by radionuclide angiography from 1970 to 1974. In each instance the systemic origin of the vascular supply was correctly indica...

Signaling by the hedgehog (hh)-class gene pathway is essential for embryogenesis in organisms ranging from Drosophila to human. We have isolated a hh homolog (Hro-hh) from a lophotrochozoan species, the glossiphoniid leech, Helobdella robusta, and examined its expression by reverse transcription polymerase chain reaction (RT-PCR) and whole-mount in situ hybridization. The peak of Hro-hh express...

The earliest signs of lung development occur around four weeks after conception with the appearance of a bud (the tracheal diverticulum) from the primitive foregut. Lung development can be described in four stages, embryonic, glandular, canalicular and sacular (TABLE 1). Towards term more subtle changes in the structure of the terminal airspaces, including elastin deposition and septation, whic...

We present a case of triple gut atresias (foregut, midgut and hindgut) with multiple congenital anomalies presenting as imperforate anus. Abdominal radiography showed the double bubble sign. Upper gastrointestinal study through a nasogastric tube confirmed duodenal obstruction. Exploratory laparotomy, duodeno-duodenostomy for duodenal atresia and a left descending colostomy for anorectal malfor...

Duplication cyst of the stomach is a rare congenital malformation, typically diagnosed in the first year of life. In most adult cases the cyst remains asymptomatic, but patients may present with abdominal symptoms including epigastric discomfort or pain. We present a case of a 65-year-old male with an asymptomatic gastric tumor diagnosed incidentally during initial workup of his esophageal aden...

Mediastinal enteric duplication cysts are a rare congenital malformation encountered mainly in neonates and infants. It is a distinct entity within the family of foregut duplication cysts. It can present with respiratory distress due to mass effect and hence surgical excision is the preferred treatment. Histologically, it is characterised by a double layered smooth muscle wall with intestinal l...

Foregut cysts are various congenital lesions originated from emberyonic foregut. Bronchogenic, enterogenous and neuroenteric cysts are the most frequent forms of foregut cysts. They create different clinical symptoms based on their location. Enterogenous cysts comprise 4-5 percent of posterior mediastinal cysts and include esophageal, gastric and enteric cysts. A 61 year old woman referred to...

Ciliated hepatic foregut cysts are uncommon solitary cysts of the liver that originate from the embryologic foregut. Clinically and radiographically, these lesions can be difficult to distinguish from neoplasms. Recent reports have demonstrated that ciliated hepatic foregut cysts may undergo dysplastic progression, supporting the argument to excise these cysts when discovered. Fewer than 100 ca...
