Computerized tomography in ventral and lateral prone position in the differential diagnosis of subdural hematoma and cortical atrophy

: The differential diagnosis between brain atrophy versus subdural effusion in children has shown some difficulties in a few cases, mainly when the frontal subarachnoid space is very large on computed tomography. We think that a simple procedure, that is, CT scans in the lateral and prone position following the standard examination, may be worth to clarify those cases of doubtful diagnosis.
