14 years, Male, nystagmus and dizziness, history of Proteus syndrome and Klippel-Trenaunay-Weber syndrome.. No structural lesions in the brain are appreciated. No significant parenchymal signal abnormality. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. No abnormal parenchymal or meningeal enhancement. Small focus of enhancement in the left frontal lobe, post gadolinium series 11 image 11, with susceptibility effect may represent a capillary telangiectasia or small developmental venous anomaly. Major flow-voids are preserved.Pituitary gland is mildly prominent in size which is within normal limits for age. There is mild to moderate opacification of the right frontal sinus and anterior ethmoid air cells and minimal opacification elsewhere in the paranasal sinuses. Bone marrow signal and extracranial soft tissues are grossly unremarkable.
1. Brain parenchyma appears within normal limits.2. Tiny focus of enhancement in the left frontal lobe with susceptibility effect which may represent a small incidental developmental venous anomaly or capillary telangiectasia.
