These lesions follow prepartum or intrapartum hypoxiaischemia and are clinically distinguished by prominent bulbar dysfunction, featuring weak or absent cry, poor feeding, and facial weakness. Neonatal thalamic calcification in premature infants may serve as a radiological marker of an acute, shortlived hypoxic-ischemic event. The presence of brain-stem dysfunction, particularly of lower cranial nerves in association with thalamic calcifications, constitutes a distinctive clinical-radiological entity and usually portends a poor outcome. The presence of these calcifications implies that injury was sustained to diencephalic and brain-stem structures at least 2 to 4 weeks prior to their appearance on computed tomographic scan.(AJDC. 1989;143:1056-1960)
