- Fig 1.
Panoramic view of the mandible (A) in bone window demonstrates involvement of the mandibular canal (dotted arrow) and dental apices (multisection spiral CT data: 64 × 0.6 mm, 120 kV, 200 mAs). CT before (B and C) and after contrast injection (100 mL; 350 mg of iodine per milliliter) (D). Expansile lytic lesion (arrow) is seen in the right mandible without cortical interruption with moderate enhancement (attenuation precontrast, 55 HU; postcontrast, 80 HU) after administration of contrast material.

MR imaging shows a lesion with low signal intensity on STIR (A, TR/TE/TI, 4100/105/140 ms; section thickness, 4 mm) and homogeneous enhancement on postcontrast T1-weighted images (B, Fat-saturated T1-weighted turbo spin-echo: TR/TE, 560/17 ms; section thickness, 4 mm; C, MP-RAGE: TR/TE/TI, 1960/3.9/1100 ms; α = 15°; SL, 1 mm) (arrow). Sagittal oblique image demonstrates involvement of dental apices and mandibular canal (dotted arrow).

Photomicrograph of the meningioma (hematoxylin-eosin, original magnification ×90) shows spindle cells partly arranged in whorls and interconnection fascicles with little interlaying collagenous matrix (A). Psammoma bodies can be identified (A, insert). Photomicrograph of tumor cells show focal staining for EMA (B, original magnification ×180) (arrows).
