retroperitoneal foregut cyst
Monday 6 June 2011
A foregut cyst is formed as a result of abnormal budding and pinching of the tracheobronchial tree when bronchial buds develop to form the primitive respiratory tree.
Foregut cysts are clinically classified as :
esophageal duplication cyst
enterogastric duplication cyst
ciliated hepatic foregut cyst.
A foregut cyst can occurr in the retroperitoneum and can be difficult to distinguish from other retroperitoneal cystic mass lesions (retroperitoneal cysts).
Magnetic resonance imaging is useful in revealing the cyst’s continuity to adjacent organs.
