A Case of Intra-Abdominal Extralobar Pulmonary Sequestration: Prenatal Detection, Postnatal Diagnostic Approach and Outcome

Abstract

This paper describes the perinatal and postnatal outcome of a case considered to have a fetal intra-abdominal extralobar pulmonary sequestration. Routine midtrimester fetal ultrasonographic scan detected an abdominal echogenic mass between aortaand stomach. It was considered primarily as an intra-abdominal extralobar pulmonary sequestration. Atpostnatal 2 months, computed tomography scan with intravenous contrast described it as an extralobarpulmonary sequestration at the level of diaphragmatic hiatus by showing the aberrant blood supply tothe sequestration with venous drainage into the portal confluence. The patient is now 4 years old andasymptomatic; she is being followed-up by a pediatric surgeon. Intra-abdominal extralobar pulmonary sequestrations usually remain asymptomatic throughout life; theymay be safely observed without surgery unless they become symptomatic or show any change in thecharacteristics of the radiologic appearance
