Male, 4 years old, status post trauma, pedestrian versus truck, GCS 15 with neck pain. Brain:No definite evidence of intracranial hemorrhage is seen. The area of concern as noted on the prior CT examination along the right aspect of the clivus shows corresponding FLAIR signal which is typical of a flow-related artifact. No other correlating findings on the other MR sequences are detected.Scalp swelling and hematoma formation are evident in the right occipital region. No parenchymal or extra-axial abnormality is seen subjacent to this region. However, there is a very subtle gyral FLAIR hyperintensity within the left frontal lobe with some associated very subtle hypervascularity in the sulci.No significant generalized mass effect is seen. No other parenchymal abnormalities are detected. The ventricles are normal in size and morphology.Cervical spine: Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. No evidence of marrow edema or marrow replacement is seen. The visualized spinal cord shows normal signal intensity and morphology. No epidural abnormalities are detected. The paraspinal soft tissues are within normal limits. There are no findings to suggest ligamentous injury.
1.No definite acute intracranial hemorrhage is seen. The area suspected to represent a small amount of blood product along the right clivus does not show convincing MR features to confirm the presence of hemorrhage. This finding may have been artifactual or it may have represented a small amount blood product which has since resolved.2.Very subtle FLAIR hyperintensity seen within the left frontal region along with very subtle associated sulcal vascularity. As this is opposite the region of right occipital scalp injury, it could represent a mild contrecoup contusion. A follow-up examination is suggested to assess for resolution.3.Assessment of the cervical spine is within normal limits. There are no findings to indicate posttraumatic injury.
