Altered mental status, unspecified [R41.82], Reason for Study: ^Reason: dbs removal. Evaluate status of inflammation. History: ams Focal susceptibility lesions are seen on the right frontal lobe where prior DBS insertion track as well as posterior aspect of right insular cavitary lesion indicating blood products.The fluid fluid level, indicating blood products within the cavitary lesion seen on the dependent portion of the cavitary lesion appears to be either significantly reduced or disappeared since prior scan.Maximum diameter was measured about 52mm x 21mm, comparing to prior scan, no significant interval change in terms of size. Surrounding edema as well as mass effects toward right lateral ventricle also do not show any significant interval change in terms of the degree and its extent since prior scan.Peripheral rim enhancement is again seen and does not show any significant interval change since prior scan.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. Decreased or disappeared fluid fluid level on the dependent portion of the rim enhancing lenticular shaped cavitary lesion at the right insular. 2. Other MR characteristics including the size and the degree of surrounding edema and mass effects do not show any significant interval change since prior scan.
