CCM disease: please evaluate for changes and lesion burden. There is a partially enhancing multiloculated cavernous malformation in the anterior left superior frontal gyrus that measures up to 23 mm. While the lesion has not significantly changed in size, the signal characteristics of the lesion have evolved, with more high T1 and low T2 signal components and decreased fluid-fluid levels. There is surrounding hemosiderin deposition diffusely, but no vasogenic edema. There is a newly apparent high T2 and intermediate T1 signal intense lesion in the subcortical white matter of the anterior temporal lobe, with susceptibility effect. There is no evidence of acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable.
1. No significant interval change in size of the cavernous malformation within the anterior left superior frontal gyrus, although the hemorrhagic contents within the lesion have evolved. 2. A newly apparent subcentimeter lesion in the anterior left temporal lobe may represent an additional cavernous malformation.
