Found unconscious at home
Patient Data
There are innumerable cortical contusions in the frontal and temporal lobes bilaterally, predominantly inferiorly, with surrounding hypodensity. There are bilateral subdural collections and locules of gas near the vertex. Blood layers in both lateral ventricles.
The ventricles are non-dilated. There is effacement of both Sylvian fissures. No midline shift.
There is a minimally displaced left parietal fracture and diastasis of the posterior sagittal and left coronal sutures. The parietal fracture extends transversely and longitudinally through the left petrous temporal bone and the anterior wall of the external auditory canal. There is opacification of the middle ear. The bony ossicles chain alignment appears normal. There is opacification of the right middle ear with no temporal bone fracture identified. There is a small left parietal scalp hematoma. There is a left periorbital hematoma. No facial fracture. The temporomandibular joints are enlocated and the paranasal sinuses are clear.
Case Discussion
Diastasis of the cranial sutures may occur with or without skull fractures.
