Known numerous CCM lesions with history of 3 craniotomies for lesion resection: headaches and seizures. There are postoperative findings related to left parietal craniotomy for resection of a left parietal cavernous malformation with unchanged diffuse susceptibility effect along the surgical cavity margins and confluent surrounding T2 hyperintensity. There are also unchanged posteroparietal findings in the left posterior fossa. There are numerous remaining supratentorial and infratentorial cavernous malformations, which are unchanged. For example, the largest remaining supratentorial lesion is located in the left anterior frontal lobe, which measures up to approximately 20 mm, and the largest infratentorial lesion is in the right cerebellar hemisphere, which measures up to 8 mm. There is no evidence of acute intracranial hemorrhage 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 unchanged.
No significant interval change in the postoperative findings and numerous remaining cerebral cavernous malformations.
