Figure 2. Chewing-induced edema of the facial muscles in 2 patients with the m.15992A>T mutation.

Figure 2

Coronal T1-weighted NMRI of the head of patient 6 (A and B) and her aunt (C and D); coronal STIR NMRI of patient 6 (E and F) and her aunt (G and H); images obtained at rest (A, C, E, and G) and 15 minutes after chewing a sandwich (B, D, F, and H). The measures show that after chewing, the diameter of temporal muscle increased by 22% in patient 6 (A vs B) and by 34% in her aunt who increased the diameter of her masseter muscle by 37% (C vs D). NMRI = nuclear magnetic resonance imaging; STIR = short-tau inversion recovery.
