ESOPHAGEAL DUPLICATION CYST ASSOCIATED WITH PULMONARY CYSTIC MALFORMATIONS

Two cases of esophageal duplication cyst associated with pulmonary cys tic malformations (cystic bronchiectasis with pneumonia in one, intrap ulmonary bronchogenic cysts with bronchial atresia in the other) are r eported. The coexistence of these complex anomalies supports the recog nition that esophageal duplication cyst also is an entity of a broad s pectrum of developmental abnormalities caused by abnormal budding of t he primitive foregut. Nine cases of similar complex anomalies in the l ung and esophagus have been reported. Although rare, this malformation complex should be borne in mind in the treatment of pediatric mediast inal and pulmonary malformations. (C) 1995 by W.B. Saunders Company
