13-week-old male status post trauma; evaluate for subdural hematoma There is prominent CSF density surrounding the cerebral hemispheres bilaterally with multiple small hyperdense foci suspicious for blood product. These hyperdense foci are best visualized on: the left frontal parafalcine region (image 12 and 13), the right frontal lobe (image 21), the left frontal lobe (image 30), the right parietal lobe (image 34), and the left parietal lobe (image 29). These findings are suspicious for posttraumatic subdural hemorrhage/hematoma of indeterminate age and should be followed up with with an MRI to evaluate the extent of parenchymal injury.There is also a area of low density consistent with edema in the posterior frontal lobe best seen on axial images 25 through 27. The ventricles and basal cisterns are normal in size and configuration. The calvaria and skull base show no fractures. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
Multiple hyperdense foci within a prominent CSF density surrounding the cerebral hemispheres, as described above, highly suspicious for posttraumatic subdural hematoma/hemorrhage. Recommend MRI for further evaluation.
