Figure 3.

MR axial (A) T1-weighted, turbo spin echo, 630/17, (B) T2-weighted, turbo spin echo 4400/72, (C) gadolinium-enhanced T1-weighted turbo spin echo images. Images demonstrate a well-defined bilobed, solid, homogenous mass centered at the anterior maxillary ridge. The mass is hyperintense to muscles and tongue on both T1W (A) and T2W (B) images, contrary to the expected findings of melanin pigment. No soft-tissue infiltration is noted. Following administration of contrast, moderate homogenous enhancement is identified (C).
