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.
