Mandibular NHL. a OPT. Difficulty to accurately identify the lesion due its median and paramedian position and the typical anterior OPT artefact (arrowheads) masking the lesion. Subtle enlargement of the right mental foramen (long arrow) compared with the normal contralateral side (short arrow). b, c T1-weighted unenhanced axial images. d T1-weighted fat-saturated contrast-enhanced sagittal image. Large infiltrative lesion (asterisks) extending from the vestibule through the mandible into the floor of the mouth (arrows). The mandibular cortical rim is mostly preserved although the lesion shows diffuse marrow infiltration
