FIG 2. Axial view MR images of a 59-year-old male patient with leptomeningeal metastases from ependymoma.

A, Unenhanced FLAIR image (10,000/147; inversion time, 2200 ms) appears unremarkable.

B, Contrast-enhanced FLAIR image (10,000/147; inversion time, 2200 ms) appears unremarkable.

C, Contrast-enhanced T1-weighted MR image (600/8) shows enhancement along the surface of the midbrain (arrowheads). Thickened, enhancing dura is also identified on the contrast-enhanced images.
