title: Prenatal ultrasonographic findings in extralobar subdiaphragmatic lung sequestration--a case report.
abstract: We present the prenatal ultrasonographic findings of an echo-dense solid mass above the normal left kidney and below the diaphragm. This mass was diagnosed as extralobar lung sequestration (ELS) at laparotomy of the child. ELS (or accessory lungs) is a rare congenital abnormality defined as a lung segment outside a normal lung, usually localized in the left lower thorax. A subdiaphragmatic localization is rare. The prognosis depends upon both the presence (as found in over 50% of reported cases) and severity of additional congenital anomalies.
