Other abnormal clinical finding [796.4], Reason for Study: ^Reason: f/u MRI History: period of transient confusion Previously seen subtle enhancing left caudate head lesion is not enhancing anymore.Instead, on T2 weighted image as well as FLAIR imaging shows focal tissue loss indicating chronic ischemic infarct.There is no evidence of additional abnormal cyst enhancement on the scan.There are bihemispheric patch minimal high signal intensity lesions on bilateral periventricular white matter and centrum semiovale indicating nonspecific small vessel ischemic disease.There is no evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and 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. Previously seen subtle enhancing lesion on the left caudate head does not show evidence of enhancement on today's scan, instead, on T2 and FLAIR images, the lesion area show subtle tissue loss, indicating small lacunar infarction.2. Minimal non specific small vessel ischemic disease.3. No evidence of acute ischemic or hemorrhagic lesion.
