With intermittent weaning training (Figure 1), respiratory function of the patient gradually improved.
Bilateral medial medullary infarction with "snake eyes appearance" in magnetic resonance imaging 9 months after onset. (A) Axial T1-weighted images showed a typical heart-shaped lesion with low signal intensity at ventral rostral medulla (arrow). (B) Different from the axial T1-weighted images, axial T2-weighted fluid-attenuated inversion recovery images showed bilateral lesions with low signal intensity which presented as a special "snake eyes appearance" at the same location (arrow). (C) Sagittal T2-weighted images revealed similar lesions with high signal intensity at ventral rostral medulla (arrow).

T2-weighted fluid-attenuated inversion recovery images 9 months after onset of quadriplegia showed lesions with low signal intensity presenting as SEA at rostral medulla level; moreover, axial T1-weighted images revealed similar lesions with low intensity at the same location (Figure 2). These findings indicated that the patient actually suffered BMMI.
