Preliminary results of a computed tomography study of neonatal brain hypoxia--ischemia.

Sixty-five neonates who suffered hypoxia or ischemia during the perinatal period underwent computed tomography (CT) of the brain. The findings were divided into six categories: local ischemia, general ischemia, intracerebral hemorrhage, subarachnoid hemorrhage, intraventricular hemorrhage, and normal. Follow-up clinical evaluation (16 patients) and CT brain scans (5 patients) were available in some patients.

Normal roentgen variant: calcaneal nutrient canal.

A canal-like radiolucency was noted in the medial plantar surface of the calcaneus in six patients. This represents a vascular canal of no clinical significance.
