Antenatal thalamic lesions in the newborn: two anatomoclinical cases

We report two cases of antenatal bilateral thalamic lesions constituted by neuronal loss, gliosis and mineralized glial or neuronal cells. No etiology could be found. Neuroradiological findings were poorly correlated with histological changes. These cases are compared with the few previously reported cases of the same condition. We strongly recommend extensive etiological investigation as recurrence occurred in one family.
