title: Infradiaphragmatic pulmonary sequestration.
abstract: The authors describe two patients with intra-abdominal pulmonary sequestration presenting as a suprarenal mass in antenatal ultrasonography (US) images. In both cases the suprarenal mass was echogenic, and in one the mass also contained small hypoechoic areas. US and computed tomography performed after birth demonstrated feeding vessels in the suprarenal mass of one neonate; colour-flow Doppler US demonstrated the smaller feeding vessels to greater advantage.
