abstract: Nine cases are reported that fulfilled the criteria for diagnosis of subdural hygroma. With the availability of serial computed tomographic (CT) scans, it is possible to document non-invasively the appearance of CSF-density subdural fluid where no prior blood accumulation has been present.
