T2-weighted magnetic resonance images, a) axial view, b) coronal view, showing a pouch with an opening and a slightly thickened wall, and a tear in the buccinator muscle on the left side (white arrow). The five-point star indicates the buccinator muscle near the pouch. Gadolinium-enhanced T1-weighted magnetic resonance images, c) axial view, d) coronal view, revealing the wall demonstrating enhancement extending over the surrounding tissues antero-posteriorly in the buccal lesion and superiorly in the maxilla on the left side, which was considered to indicate an inflammatory reaction (white arrow)
