Multimodal Virtual 3D Representation of a Giant Cell Tumor of the Thyroid Cartilage.

Virtual three-dimensional (3D) scanning of pathologic specimens may allow for improved communication between the surgeon and pathologist, as well as enhanced patient counseling and engagement. We report the rare case of a giant cell tumor of the thyroid cartilage and present a multimodal 3D representation. Preoperative 3D printing of the anatomic structures from cross-sectional imaging, as well as novel ex vivo 3D scanning of the fresh pathologic specimen for virtual 3D specimen mapping, was performed.
