Figure 1. (A) Anteroposterior and (B) lateral views of esophagram. Barium retained at the level of esophageal entrance (arrows) and entered the trachea.
Figure 2.
Figure 2. EMG of the left CPM before and after BTX treatment. (A) Incomplete inhibition of muscle contraction was present during the hypopharyngeal phase of swallowing (between arrows). (B) After BTX injection, CPM contraction amplitudes were decreased at rest compared to pre-treatment of BTX (upper green trace). Normal inhibition of CPM contraction was present during swallowing (between arrowheads).

Figure 4.
Figure 4. Follow-up T2-weighted imaging before and after onset of dysphagia. (A) No medullary syrinx at 2 years ago. (B) The left medullary syrinx was present at 6 months ago. (C) Axial, (D) sagittal and (E) coronal views of heavy T2-weighted spin-echo inverted imaging showed bilateral extension of medullary syrinx after bulbar onset.
