FIG 1. Axial view MR images of a 41-year-old male patient with leptomeningeal metastases from laryngeal squamous cell carcinoma.
A, Unenhanced FLAIR image (10,000/147; inversion time, 2200 ms) shows diffuse abnormal signal intensity in the subarachnoid space (arrowhead).
B, Contrast-enhanced FLAIR image (10,000/147; inversion time, 2200 ms) shows diffuse abnormal signal intensity in the subarachnoid space (arrowheads).
C, Contrast-enhanced T1-weighted MR image (600/8) is falsely negative. Parenchymal metastasis is also identified (arrow).
