case_images: After removal of dental braces, MRI demonstrated continued leptomeningeal enhancement and a new enhancing intramedullary lesion at C7-T2 measuring 4 x 17 mm2 (Figure 1).
case_images: Our patient's progression of perivascular cystic development from initial presentation (A) to 3 months later (B).

case_images: There were also an increased number and size of cysts inferiorly and bilaterally in the brain, thought to represent abnormal dilatation of the perivascular spaces (Figure 2), consistent with previous biopsy findings.
