Status post CCM resection with seizures. There are postoperative findings related to right parietal craniotomy with linear enhancement within the resection cavity and a residual adjacent developmental venous anomaly. There is also unchanged confluent T2 hyperintensity in the surrounding white matter, which may represent gliosis, as well as scattered areas of susceptibility effect that likely represent hemosiderin deposition. There is no evidence of acute intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. 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 unchanged.
Postoperative findings related to right parietal lobe cavernous malformation resection with a residual adjacent developmental venous anomaly, linear enhancement in the resection cavity that may represent granulation tissue, and surrounding white matter signal abnormality that likely represents a combination of hemosiderin and gliosis.
