CCM: Migraines. There is a 5 mm diameter T1 and T2 hyperintense lesions with complete peripheral susceptibility effect in the posterior right medial orbitofrontal gyrus. There is an adjacent anterior right frontal lobe developmental venous anomaly. There is no evidence of intracranial hemorrhage, vasogenic edema, 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, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Unchanged small posterior right medial orbitofrontal gyrus cavernous malformation with an associated developmental venous anomaly, but no evidence of acute intracranial hemorrhage.
