Abstract | OBJECTIVE: METHODS: We analyzed 3 cases from our institution and reviewed 12 published cases of PDHD and 6 cases of PCD, recording all of the ultrasound signs, as well as magnetic resonance findings when available. Because of the small number of cases of PCD, we also included postnatal signs that could have been observed during imaging during pregnancy, for a total of 11 cases of PCD. RESULTS: We conclude that PDHD can be suggested in the presence of ventriculomegaly or paraventricular cysts, associated with an abnormality of the cerebral parenchyma such as abnormal gyration or involvement of the corpus callosum. Pyruvate carboxylase deficiency can be suggested in the presence of ventriculomegaly, frontal horn impairment associated with subependymal, and paraventricular cysts. CONCLUSION: When confronted to the ultrasound abnormalities we described, and after eliminating the most frequent etiologies, a metabolic deficiency should be considered. Furthermore, the hereditary character of these diseases makes that it is important to send the family with genetic advice in particular in case of history of a fetal death in utero or a death neonatal unexplained.
