 There are few non-specific foci of T2/FLAIR signal hyperintensity in the left frontal lobe. Linear enhancement within the inferior left frontal lobe may represent a developmental venous anomaly. Otherwise, there is no abnormal enhancement in the brain, evidence of intracranial mass, mass effect, or midline shift. No diffusion weighted abnormalities are identified. There is no evidence for intracranial hemorrhage. No mass is identified in the cerebellopontine angles, and there is no obvious abnormal facial nerve enhancement. The ventricles and sulci are normal in size. There are no extraaxial fluid collections or subdural hematomas. The paranasal sinuses and mastoid air cells are clear. There is a 1 cm benign appearing lesion centered in the outer table of the right parietal bone which demonstrates increased T2 signal and enhancement on postcontrast imaging with mineralization evident on prior CT, which may represent an intraosseous meningioma or hemangioma.
1. MRI of the brain is essentially within normal limits for age. Specifically, no evidence of acute infarct or intracranial mass. A few foci of T2 hyperintensity in the left frontal lobe are nonspecific, but may relate to prior inflammation or can be seen with entities such as migraines.2. Enhancing lesion in the right parietal calvarium with mineralization evident on recent CT. Lesion is nonspecific but favored to represent a benign entity suggest as atypical hemangioma or intraosseous meningioma
