a–c Autosomal recessive polycystic kidney disease in a foetus at 17 weeks gestation, following termination of pregnancy. The post-mortem imaging was obtained 8 days after delivery. The sagittal post-mortem ultrasound images of the right (a) and left (b) kidneys demonstrate poor corticomedullary differentiation, numerous hyperechoic foci and a hyperechoic renal cortex in keeping with numerous renal microcysts. The corresponding post-mortem T2 weighted MRI in coronal plane (c), also shows enlarged kidneys with small microcysts and a normal appearing liver. At autopsy, the photograph taken of the retroperitoneum, with both kidneys in situ (d), shows the large size of these organs, occupying almost the entire abdomen
