Abstract
A consecutive series of 100 children with neurological diseases or head trauma were examined by means of computerized tomography. A high incidence of bifrontal low density area (BELD) was found in cases below 2 years of age, especially between 6 and 12 months, while BELD was much less common in cases above 2 years of age, though most of them had neurological symptoms and/or signs. Most cases with follow-up CT scanning had increases in width of BELD at the ages of 6 to 12 months. The results suggest that the trend of CT findings related to age in the present study may reflect physiological changes of the space between the skull and the brain with age.
The most characteristic CT findings in 4 cases with chronic subdural hematoma were a crescent-like BELD with a relatively linear contour on the cerebral cortex and a wider BELD than that of dilated subarachnoid space. Other findings included an asymmetry in width of BELD and interhemispheric low density area and less prominent sulci than those in cases with dilated subarachnoid space.
