Clinical question: Blunt trauma. Signs and symptoms: Loss of consciousness. Nonenhanced head CT:There is no evidence of intracranial hemorrhage, edema, mass-effect, midline shift or hydrocephalus.The cortical sulci, ventricular system, CSF cisterns and gray -- white matter differentiation is within normal limits. Very small focus of low-attenuation in the periventricular white matter is believed to represent a small was ischemic disease as was noted on prior MRI examcalvarium is intact. No evidence of hemorrhage or swelling of the scalp is detected.Mastoid air cells and middle ear cavities are pneumatized and unremarkable.Visualized paranasal sinuses are unremarkable.Limited images through the orbits are unremarkable.
With the exception of minimal small vessel ischemic disease of indeterminate age this study is within normal limits.
