Subdural effusions in children under two years--clinical and computer-tomographical data.
We investigated 161 children under 24 months of age by CT of the skull and reviewed the anamnestic and clinical history. 87 children showed subdural effusions, and 74 did not. There were 33 patients with other pathological findings in CT, and 41 had normal scans. Age and sex distribution as well as localization of the subdural effusions were consistent with the literature. The 87 children with subdural effusions represented 1.7% in a sample of about 5.000 CT scans. CT was the most reliable method for diagnosis of subdural effusions, compared to other techniques. There was a preponderance of small subdural effusions from 1 to 7 mm thickness (51%). Other CT abnormalities accompanying subdural effusions were found. Most frequently the interhemispheric sulcus was dilated and an internal hydrocephalus was present. Also in our group there were 7 anamnestical and 6 clinical symptoms highly diagnostic of subdural effusions.
