[Symptomatic calcification in the newborn. Phenocopies of chondrodysplasia punctata]

Stippled epiphyses occur in the new-born and young infant in the different hereditary forms of chondrodysplasia punctata. Symptomatic stippling has been described also in association with chromosomal anomalies, gangliosidosis and drug induced embryopathies. We present patients with Cumarin-embryopathy (2), fetal alcohol syndrome (1), Zellweger-syndrome (2) and chromosomal anomaly 16 (1) and discuss the typical roentgenographic features, distribution and differential diagnosis of epiphyseal stippling.
