case_images: Transverse T2 MRI images of the patient showed no swallow-tail signs indicating degeneration of the reticular parts of the substantia nigra and red nuclei (Fig. 1).
case_images: Patient single-photon emission computed tomography images. There was asymmetrical uptake in the caudate nucleus (white arrows).

case_images: In addition, SPECT and PET images showed asymmetrical oval-shaped, rather than comma-shaped, dopamine uptake (Figs. 2 and 3).
case_images: Patient positron emission tomography-computed tomography images. The comma-shape deteriorated to an oval-shape.
