Muscle weakness (generalized) [M62.81], Reason for Study: ^Reason: ischemic stroke History: as above There is no evidence of acute ischemic lesion on the scan.There are however multifocal susceptibility lesions involving left side insular cortex, basal ganglia, posterior temporal lobe, left thalamus and the left cerebellar hemisphere. Among them, left thalamus lesion measured about 9.5 mm with periportal T2 low signal intensity lesions indicating hemosiderin deposition. Constellation of these findings suggest a possible cavernous malformations.There is no evidence of associated developmental venous anomaly on this scan.Scattered bihemispheric periventricular and centrum semiovale T2/flair high signal intensity lesions are seen. These lesions are nonspecific but may indicate related to small vessel ischemic disease.The ventricles, sulci and cisterns are 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 lesion.2. Multifocal susceptibility lesions with the largest lesion on the left thalamus, differential diagnosis include cavernous malformations, prior multifocal hemorrhages, parenchymal mineralizations.3. Non specific small vessel ischemic disease.
