Headache. There are scattered T2 hyperintense foci throughout the frontoparietal white matter. The largest of the lesions in the left parietal white matter is associated with facilitated diffusion without restriction. The lesions are noncontrast enhancing and are nonspecific in distribution and morphology. There is no space occupying brain lesion. There is no intracranial hemorrhage. The ventricles are mildly dilated. The other CSF-containing spaces are normal in size. Major intracranial vessels are patent.The orbits are normal. Mastoid air cells are clear. There is minimal mucosal thickening in the ethmoid and sphenoid sinuses without fluid. The other paranasal sinuses are clear. There is no skull destructive lesion.
1.Scattered frontoparietal white matter lesions are nonspecific in appearance and distribution. Such lesions are usually related to chronic microvascular ischemia.2.There is very minimal mucosal thickening in the ethmoid and sphenoid sinuses without fluid.
