Fetal imaging prompts maternal diagnosis: autosomal dominant polycystic kidney disease

Autosomal dominant polycystic kidney disease (adpkd) is a common inherited disorder. ultrasound (us) findings can include enlarged echogenic kidneys in utero and cysts in multiple organs in adults. though a highly penetrant disease, due to varied clinical expression and the typical late onset of symptoms, reproductive-aged women may not know their carrier status. we present two cases in which fetal us findings suggested adpkd and additional evaluation identified likely maternal adpkd as well.
