Female, 54 years old, with left sixth nerve palsy. A focus of subcortical T2 hyperintensity is present within the right superior frontal gyrus. No associated mass effect is seen. A few additional scattered small foci of white matter T2 hyperintensity are demonstrated elsewhere in the brain.No evidence of restricted diffusion is seen. No parenchymal edema or mass effect is detected. On postcontrast images, there is no evidence of any pathologic parenchymal or extra-axial enhancement.No intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. The ventricles demonstrate normal size and morphology.The globes are symmetric and round. The extraocular muscles demonstrate normal morphology and enhancement. The optic nerves, chiasm and visualized optic tracts are within normal limits. No abnormalities of the cavernous sinus are seen.The cranial nerves are within normal limits. In particular the sixth cranial nerves are visualized as they traverse the prepontine cistern and are normal.
1.A focus of T2 hyperintensity within the right superior frontal gyrus is nonspecific but could reflect the sequela of prior trauma or perhaps a chronic ischemic lesion.2.No acute intracranial abnormalities are seen.3.The orbits, cavernous sinuses and visualized cranial nerves are within normal limits.
