Findings
Findings
CT images of the head demonstrate a large bilateral occipital parietal and left temporal subgaleal hematoma. Deep to this, there is a nondisplaced linear skull fracture arising from the right lambdoid suture extending inferiorly into the left, decompressing into the left occipital suture. Minimal diastases is present of the fracture as well as the adjacent suture.
Intracranially, there is venous tethering injury with blood products in the left occipital lobe. Subdural blood products are present collecting along the posterior falx.
Examination of the posterior fossa demonstrates diffuse edema with effacement of the prepontine cisterns. There is upward transtentorial herniation without definite progressive downward tonsillar herniation. There is diffuse sulcal effacement of the supratentorial brain, but the gray-white matter differentiation is maintained. The fourth ventricle is effaced and there is mild dilatation of the lateral and the third ventricles consistent with obstructive hydrocephalus.
The orbital structures are unremarkable. The mastoid air cells and paranasal sinuses are well aerated and free of disease.
Impression
subgaleal hematoma.
2. Small areas of subarachnoid hemorrhage in the left occipital lobe with small volume
extra-axial blood products collecting along the posterior falx.
3. Diffuse edema with upward transtentorial herniation.
