A 45-year-old-man with popliteal mass, calf pain radiating into the big toe, and no personal or family history of tumors, café-au-lait spots, or hearing difficulties. (a) Sagittal T2-weighted CAIPIRINHA SPACE (Siemens Healthcare) three-dimensional (3D) MR image demonstrates the morphologic features of a tibial schwannoma, including a hyperintense intraneural mass (arrow) with single proximal and distal fascicular connections. (b) Virtual gross anatomy cinematic rendering MR image of the popliteal region demonstrates the schwannoma (arrow) through simulation of a surgeon's in situ perspective following surgical exposure. Cinematic rendering is a postprocessing technique that can create photograph-realistic images from 3D MRI datasets through the simulation of interactions of visible photons with the MR image anatomy. (Cinematic rendering software not 510K approved for patient care in the United States.)
