 Head: There are no T2/FLAIR signal abnormalities. There is redemonstration of a ventricular catheter with right frontal approach that terminates in the upper third ventricle. The ventricular size is normal. There is no midline shift. Basal cisterns are patent with no evidence of herniation. There is no acute hemorrhage or mass effect. Vascular flow voids are within normal limits. There is no diffusion restriction. There is thickening of the scalp along the right frontal region. There is susceptibility artifact along the right parietal region, perhaps related to a piece of metal in the scalp, as seen in the previous CT. There is opacification of the mastoid air cells. There is partial opacification of the paranasal sinuses.Cervical spine: There is redemonstration of fracture of the base of the dens, which extends obliquely through the right lateral body of C2. Remainder of the vertebral bodies have normal signal. There is a subtle punctate T2 high signal in the left hemicord at the level of C3 on axial imaging, which is not confirmed on sagittal T2 imaging. There is airspace disease in the pulmonary right upper lobe and right-sided pleural effusion.
1.No acute hemorrhage or mass effect in the brain parenchyma. There is no evidence for acute ischemic cerebral infarction.2.Cervical spine demonstrates fracture of the base of the dens which is better appreciated on recent CT of the cervical spine. 3.There is a subtle punctate T2 high signal in the left hemicord at the level of C3, which is likely artifactual.4.The patient status post ventriculostomy tube placement.5.The patient is known to have temporal bone and skull base fracture. Please refer to CT of the temporal bones for further comments
