case_images: The magnetic resonance imaging (MRI) results only showed mild abnormal signals around the midbrain aqueduct in T2/fluid-attenuated inversion recovery (FLAIR) (Figure 1).
case_images: MRI of the patient during his second time in the hospital, T2/fluid-attenuated inversion recovery (FLAIR) showing abnormally high signals around the midbrain aqueduct, around the fourth ventricle, and in the dentate nuclei of the cerebellum bilaterally (arrows).

case_images: A second MRI examination showed abnormal signals around the midbrain aqueduct, around the fourth ventricle, and in the dentate nuclei of the cerebellum bilaterally in T2/FLAIR (Figure 2).
case_images: MRI reexamination of the patient after drug withdrawal during his second time in the hospital, T2/fluid-attenuated inversion recovery (FLAIR) showing abnormally high signals around the midbrain aqueduct, around the fourth ventricle, and in the dentate nuclei of the cerebellum bilaterally, which disappeared 9 days after drug withdrawal.
