  		Fig 1. T2-weighted axial view images (A and B) show linear increased signal intensity in the left lateral medulla in the left spinotrigeminal nucleus and tract and left solitary nucleus. A coronal 3D-CISS image (C) demonstrates no compression of the trigeminal nerve at the pontine nerve root entry zone.

  		Fig 2. Coronal and axial sketches of the medulla, which correspond to the medullary regions seen on the T2-weighted axial images in Fig 1, demonstrate the anatomical proximity of the spinotrigeminal nucleus and tract to the solitary nucleus and nucleus ambiguus.
