Male, 30 years old, with headache status post head trauma in motor vehicle accident. No evidence of hyperintense signal abnormal is seen in the area of suspected chronic hemosiderin staining in the high right frontal lobe. A small patch of nonspecific hyperintensity is evident in the left parietal white matter. No significant parenchymal edema or mass effect is detected. Prominence of the CSF space anterior to the left temporal lobe, completely suppressing on FLAIR, may represent an incidental arachnoid cyst, appearing similar to prior.
No acute intracranial abnormality. Also noted is prominence of the CSF space anterior to the left temporal lobe which may represent an incidental arachnoid cyst.
