History of left temporal lobe from meningioma resection, auditory and visual hallucinations, suspicious for encephalitis. No evidence of acute ischemic or hemorrhagic lesion.There is about 4mm sized intensely enhancing area (series 901, image 113/300) on the right basal ganglia, likely globus pallidus on enhancement. However, this is the only abnormal enhancement on this scan. Therefore, it is likely to be a vascular enhancement such as focal dilated venous structure. Possibility of arterial aneurysm is low.Therefore, if clinically indicated, follow up MRI with contrast enhancement can be considered.Redemonstration of left temporal lobe anterior aspect large resection cavity with the surrounding gliosis indicating postoperative changes. These are showing no interval changes since prior scan.Patch high signal intensities on FLAIR images on bilateral periventricular white matter indicating minimal to mild nonspecific small vessel ischemic disease, no change since prior scan.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. No evidence of acute ischemic or hemorrhagic lesion. 2. Focal intensely enhancing area on the right basal ganglia which likely represent vascular structure such as dilated venous structure. 3. Post resection status of the left temporal area meningioma with post operative changes, no interval change since prior exam.4. Non specific small vessel ischemic disease. No change since prior exam.
