Figure 1. Magnetic resonance imaging 14 months after onset
T2-weighted image showing high intensity confined to a small region of
the left dorsolateral medulla (yellow arrow).
Figure 2. Videofluoroscopic examination of swallowing 14 months after
onset
Severe bolus residue in the pyriform sinus owing to weak pharyngeal
contraction and an impaired UES relaxation.
Figure 3. Pressure topographies of the patient (a) and of a normal
subject (b)
Spatiotemporal plots of dry swallows. Y-axis, catheter position; X-axis,
time. Pressure is indicated using the color scale. Maximum pharyngeal
pressures measured at the velopharynx and meso-hypo pharynx. UES
relaxation duration and UES pressure during swallowing are evaluated.
UES: upper esophageal sphincter.
