Dystonia, unspecified [G24.9], Reason for Study: ^Reason: Follow up progression abnormal right external capsule lesion History: left hand dystonia Redemonstration of the right insular cortex and external capsular FLAIR/T2 high signal intensity lesions with mild volume loss with corresponding CSF space dilatation, unchanged since prior scan. There is no evidence of acute ischemic or hemorrhagic lesion on this scan.The ventricles, sulci and cisterns are unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. 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. Right insular cortex and external capsule FLAIR/T2 high signal intensity lesions with volume loss, unchanged since prior scan.2. No evidence of acute ischemic or hemorrhagic lesion.
