FD American Society of Neuroradiology SP 175 OP 179 VO 22 IS 1 A1 Kim, Hyung-Jin A1 Choi, Sung-Kyu A1 Lee, Choong Jae A1 Suh, Chang Hae YR 2001 UL http://www.ajnr.org/content/22/1/175.abstract AB Summary: We report a case of aggressive epithelial odontogenic ghost cell tumor arising from the mandible in a 32-year-old man. On CT and MR studies, the tumor was seen as a large, heterogeneous soft-tissue mass that caused marked destruction of the mandible and invaded the mouth floor and tongue base. The tumor displayed a variety of densities and signal intensities on CT and MR images, which correlated well with the degree of cellularity of epithelial islands, abundance of ghost cells and eosinophilic materials, calcification, and cystic areas on histologic sections. Owing to the unpredictable biological behavior of this type of tumor, careful, long-term follow-up is highly recommended.
