Cavernoma resection. There are postoperative findings related to left posterior midbrain cavernous malformation resection with a small amount of susceptibility effect along the margins of the surgical cavity. There is also a punctate focus of enhancement along the medial aspect of the surgical cavity as well. However, the surrounding edema has essentially resolved. There is no evidence of acute infarction. There is a prior right transfrontal ventricular shunt tract. The ventricles are unchanged in size. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Interval evolution of postoperative findings related to left posterior midbrain cavernous malformation resection with what likely represents a small amount of residual peripheral components of the otherwise grossly resected cavernous malformation, but the surrounding edema has essentially resolved.
