Hypophosphatasia(HPP)is rare and inherited bone disease that features failure of bone calcification caused by low serum alkaline phosphatase(ALP)activity. Asfotase alfa, enzyme replacement therapy, was approved in 2015 and significantly improved survival in patients with severe HPP. Fetal diagnosis by image is challenging, but pattern of hypomineralization and metaphyseal characteristic may help distinguish HPP from other skeletal dysplasias. Here, we report two cases of perinatal HPP who underwent fetal CT and treated with asfotase alfa from day 0. Following enzyme replacement therapy, skeletal mineralization has improved with no remarkable side-effects.
