47-year-old male with cavernous malformation. There is a 6 mm diameter lesion with extensive peripheral susceptibility effect and punctate central T1 and T2 hyperintensity in the white matter anterior to the frontal horn of the left lateral ventricle, unchanged in appearance, without perilesional edema. There is perhaps a tiny adjacent developmental venous anomaly. There are no other similar appearing lesions. Redemonstrated are a few scattered punctate foci of T2 hyperintensity in subcortical white matter locations without mass effect, restricted diffusion, susceptibility abnormality, or enhancement. There is no evidence of intracranial hemorrhage or acute infarct. The brainstem and cerebellum appear unremarkable. 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 skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. The right globe is elongated with a scleral buckle and lens implant.
1.Stable 6 mm diameter lesion in the white matter anterior to the frontal horn of the left lateral ventricle likely represents a cavernous malformation. 2.Stable minimal punctate white matter T2 hyperintense foci, statistically most likely due to small vessel disease.
