Paresthesias, urinary frequency, and diplopia. There is linear branching enhancement with associated susceptibility effect and mild T2 hyperintensity in the right pons. There are also punctate foci of patchy enhancement and associated susceptibility effect within the right inferior frontal lobe. The brain parenchyma otherwise appears unremarkable. There is no evidence of intracranial hemorrhage, mass, 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 mild scattered paranasal sinus mucosal thickening.
1. Linear branching enhancement with associated susceptibility effect and mild T2 hyperintensity in the right pons is compatible with a developmental venous anomaly.2. Punctate foci of patchy enhancement within the right inferior frontal lobe may also represent developmental venous anomalies or telangiectasias.3. No evidence of intracranial demyelinating lesions.
