Figures
- Fig 1.
A representative case (patient 1) showing the abnormal signals at the paravermal area and the middle cerebellar peduncle. FLAIR axial images (A and B), a coronal image (C), and a sagittal image (D) show atrophy of the cerebellum and bilateral high signal intensity in the medial part of the cerebellar hemisphere immediately beside the vermis (the paravermal area) (black arrows) and in the middle cerebellar peduncle (black arrowheads).
- Fig 2.
Patient 4. DWI (A) shows high-intensity signal along the corticomedullary junction. A FLAIR axial image (B) shows diffuse high intensity in the bilateral cerebral hemispheres. FLAIR axial (C) and coronal (D) images show atrophy of the cerebellum and high-intensity signal in the medial part of the cerebellar hemisphere right beside the vermis (the paravermal area).
- Fig 3.
Patient 2. A FLAIR axial image shows bilateral high signal intensities in the middle cerebellar peduncle.
