case_images: A pedunculated, rubbery, nontender, and pinkish mass of gingival-like tissue was seen extending from lower left first premolar to lower left second molar, occupying entire lower left buccal vestibule (Figure 1).
case_images: T1-weighted axial image showing well-marginated isointense soft tissue lesion with few hypointense areas within.

case_images: T1-weighted sequences (Figures 2 and 3) and iso- to hypointense on T2-weighted sequences (Figure 4). Multiple small hypointense areas were seen within the mass on nonenhanced T1-weighted sequences suggestive of calcifications. The mass had caused displacement of zygomaticus major muscle and facial artery, but the fat planes were preserved.

case_images: T1-weighted sequences (Figures 2 and 3) and iso- to hypointense on T2-weighted sequences (Figure 4). Multiple small hypointense areas were seen within the mass on nonenhanced T1-weighted sequences suggestive of calcifications. The mass had caused displacement of zygomaticus major muscle and facial artery, but the fat planes were preserved.
case_images: T2-weighted axial image showing iso- to hyperintense mass.

case_images: T1-weighted sequences (Figures 2 and 3) and iso- to hypointense on T2-weighted sequences (Figure 4). Multiple small hypointense areas were seen within the mass on nonenhanced T1-weighted sequences suggestive of calcifications. The mass had caused displacement of zygomaticus major muscle and facial artery, but the fat planes were preserved.
