Baseline assessment of CCM lesions. There are numerous, perhaps greater than 50, supratentorial and infratentorial lesions with susceptibility effect. The largest of these measures up to 13 mm in the left parietal lobe. There is no evidence of associated developmental venous anomalies or vasogenic edema. There is also no evidence of acute intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is right paranasal sinus mucosal thickening.
Numerous supratentorial and infratentorial cavernous malformations.
