17 year-old female status post fall with double vision and headache, loss of consciousness and blood from left ear canal. There is no evidence of intracranial mass or edema. A small focus of high density presumably represents an extra-axial fluid collection adjacent to the frontoparietal cortex, (images 12 and 13). Focus of soft tissue density overlying the left parietal occiput likely represents a hematoma without underlying fracture.These focal findings suspicious for a small subdural hematoma would be better evaluated with an MRI.Low-density focal widening of the right lateral sylvian fissure may represent an arachnoid cyst (image 7).The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
1. Small focus of hyperdensity, as described above, may represent a subdural hematoma which would be better evaluated with MRI.2. Other findings as described above.
