Figure 3. Ultrasonography images revealed bulky left masseter muscle, with mild heterogeneous structure, and evidence of 2 rounded calcified foci (A, arrow), with calcification-related distal acoustic shadowing (B, arrows). Venous flow is detected on color Doppler images (C, D). No arterial waveform noted on spectral flow analysis; images not shown. Ultrasonography images with clenching of teeth revealed superficial facial hernia defect overlying left masseter muscle with focal muscular herniation through it (C, arrows), which is improved by stopping clenching of teeth (D).
