case_images: Neurological examination was unremarkable on admission; however, binaural deformation was present (Figure 2).
case_images: Brain CT scan showing calcification (arrows), which can be seen in the polychondritic ears (A). DWI shows abnormal signals in the bilateral auricles (B, arrows). T1-weighted MRI with contrast showed abnormal signals and thickening of both ears (C, arrows) and increased enhancement of the pia mater (D).
