Newborn who experienced oligohydramnios in utero

CXR and US of autosomal recessive polycystic kidney disease causing oligohydramnios and pulmonary hypoplasia
CXR AP (above) shows a small bell-shaped thorax with poorly expanded lungs despite being on a ventilator. Transverse US of the left kidney (below left) and right kidney (below right) shows the kidneys bilaterally to be enlarged and to be composed of innumerable microcysts giving the kidneys overall an echogenic appearance.

The diagnosis was autosomal recessive polycystic kidney disease resulting in oligohydramnios resulting in pulmonary hypoplasia.
