Evaluation of suspected right frontal lobe cyst on OSH MRI. There is a cluster of cystic spaces in the subcortical white matter of the anterior right frontal lobe that collectively measure up to 20 mm. There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. 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.
A cluster of cystic spaces in the subcortical white matter of the anterior right frontal lobe that collectively measure up to 20 mm are compatible with focally enlarged perivascular spaces.
