40 year-old female with trauma and neck pain. Evaluate for bleed. There is no evidence of intracranial hemorrhage or abnormal extra-axial fluid collections. There is asymmetric low attenuation within the left temporal lobe, which may represent contusion versus artifact from beam hardening. Repeat CT or MRI is recommended for further evaluation if clinically indicated.The remainder of the cerebral and cerebellar hemispheres and brain stem demonstrate normal morphology and attenuation. Ventricles are midline, with normal volume and morphology. The basilar cisterns are normal in appearance.The calvaria are intact, with no evidence of fracture. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
