FIG 3. Axial FLAIR (A) and diffusion-weighted images (B) from the initial MR imaging examination both demonstrate hyperintensities in the thalami bilaterally. The hyperintensities are more obvious on the diffusion-weighted image. Axial FLAIR (C) and diffusion-weighted images (D) from the follow-up MR imaging examination 9 months later show no abnormal signal intensities in the thalami bilaterally. No brain atrophy is found. The abnormal signal intensity in the bilateral front lobes on both the FLAIR and diffusion-weighted images results from the artifact. The follow-up diffusion-weighted image (D) was obtained only using a superoinferior gradient.
