Male 20 years old Reason: Evaluate for DAI History: Fell off bicycle, possible DAI read on CT head. There is no evidence of intracranial hemorrhage. Hypoattenuating focus on CT corresponds to a focus of T2 hyperintensity in the subcortical white matter of the right frontal lobe. There are additional small foci of periventricular and subcortical white matter T2 hyperintensity in both frontal lobes and parietal lobes. The brain parenchyma and pituitary gland appear unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1.No evidence of acute intracranial hemorrhage. 2.Focus of T2 hyperintensity in subcortical white matter of the right frontal lobe with additional small foci of white matter T2 hyperintensity. These findings are nonspecific, but are unlikely related to nonhemorrhagic diffuse axonal injury. These findings may be seen in the setting of chronic migraine headaches, demyelinating disease, as well as migrational abnormalities. Clinical significance of this lesion is unclear.
