High attenuation gyri CT in postasphyxial encephalopathy.
Two term infants suffering severe asphyxial events were found to have diffusely high attenuation of the cortical gyri on CT scanning within 12 days. The findings are consistent with haemorrhagic necrosis or microcalcification. This feature has rarely been described in the literature. The evolution of the CT appearance, the possible neuropathological findings and the relationship with hypoxic-ischaemic encephalopathy are discussed.
