Clues and pitfalls in the early prenatal diagnosis of ‘late onset’ infantile polycystic kidney

Infantile polycystic kidney disease (IPKD) is an autosomal recessive inherited disorder, IPKD has been previously diagnosed by us as early as the 14th week of gestation. 'Late onset' (third trimester) IPKD has been previously described by several authors. We present here a case of intrauterine detection of 'late onset' IPKD, suggesting that elongated hyperechogenic kidneys (with normal transverse and anteroposterior diameters) should be considered as an early sign of 'late onset' presenting IPKD.
