Presentation
Incidental finding.
Patient Data
A well-circumscribed subcortical right anterior temporal cystic lesion is present with a halo of surrounding FLAIR signal abnormality. Small loculated components are seen at the anterolateral margin. A few prominent additional perivascular cysts are seen adjacent to the lesion. Additional CISS and TOF MRA imaging confirm vessel notching at the anterosuperior margin of the lesion, a classical appearance for perivascular spaces in this location.
Conclusion: Imaging features characteristic of an anterior temporal pole perivascular space.
Case Discussion
This individual has had follow-up for over 3 years and no change whatsoever has occurred. Features are characteristic of an anterior temporal pole perivascular space.
