Case Report of an Enteric Cyst Diagnosed Antenatally and the Differential Diagnosis of Fetal Mediastinal Cystic Masses

Abstract

Fetal mediastinal cystic masses occur rarely. We present a case in which a large fetal mediastinal cystic mass was visualized at the first antenatal visit in the third trimester of pregnancy. A 4-week ultrasonographic follow-up demonstrated the slow growth of the mass until delivery, when the fetus was considered to he mature. Removal of the entire cyst was performed 8 h after abdominal delivery, and the newborn did well postoperatively. The histopathologic examination of the removed cystic mass showed an enteric cyst. We also reviewed the differentia! diagnosis of the fetal mediastinal masses. © 1994 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
