 There is a small 9-mm AP by 10-mm craniocaudal by 5-mm transverse enhancing lesion with a broad dural base along the posterolateral-most aspect of the right temporal lobe (series 11 image 14, series 1401 image 31, series 14 image 137). There is no associated underlying parenchymal signal abnormality.There are scattered foci of T2 hyperintensity within the white matter without associated mass effect, restricted diffusion, susceptibility abnormality, or enhancement. The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. No diffusion-weighted abnormalities are identified. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain parenchyma.

There is no associated underlying parenchymal signal abnormality. Although the differential diagnosis would include a metastasis, lymphoma, or granulomatous disease, an incidental meningioma is more likely.2.Chronic small vessel ischemic disease.
