One year follow-up scan status post craniotomy for left temporal CCM resection. There are post left temporal craniotomy changes including susceptibility artifact related to hardware. There has been interval decrease in the amount of high T2 signal surrounding resection cavity within the left temporal lobe. There remains a small rim of high T1 signal and susceptibility effect consistent with the presence of hemosiderin. Otherwise, there is no residual mass, fluid collection, hemorrhage, hydrocephalus, or acute ischemia. The midline is intact. The left mastoid fluid has resolved.There is a small mucus retention cyst within the right maxillary sinus. The orbits are unremarkable.
Expected interval evolution of postoperative findings related to the resection of the left temporal cavernous malformation with minimal residual hemosiderin in the surgical bed.
