Status post resection for CCM; post-op follow up; 3T Scanner, CCM Protocol, QSM/Permeability The patient is status post left-sided craniotomy for a left parietal lobe lesion which has been removed. There is associated dural thickening and enhancement underneath the craniotomy flap. Cortically based lesion has been removed. There still some susceptibility effect along the adjacent brain tissues which is likely related to hemosiderin deposition.There are several periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images. These are nonspecific and likely of little clinical significance. They have been present since previous exams and are not changedNormal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.There is a 5x8mm enhancing lesion present along the superficial portion of the right frontal bone the right frontal scalp soft tissues associated with the skin deformation. This is also evident on the prior head CT as well as old MRI scans dating back to 2011.
1.Status post removal of left parietal lobe cerebral cavernous malformation. There is some local postoperative change and residual hemosiderin deposition related to the previous CCM but no convincing evidence for residual of recurrent CCM.
