Central odontogenic fibroma of the jawbone: 2 case reports describing its imaging features and an analysis of its DCE-MRI findings.
Odontogenic fibroma (OF) is a rare nonepithelial benign tumor arising from the odontogenic mesenchymal tissue in the jawbone. OFs are topographically categorized into 2 types, the central type and peripheral type, and are histopathologically divided into the epithelium-poor type and epithelium-rich type. The radiological findings of central OF commonly include a uni- or multilocular radiolucent area with a well-defined margin, which are similar to those of cysts and other benign tumors of the jawbone. Therefore, it is difficult to distinguish OF from these jawbone lesions on radiographs because of their noncharacteristic radiological findings. In this article, we report the cases of 2 patients with central OF who underwent magnetic resonance (MR) examinations and describe the usefulness of dynamic contrast-enhanced MR imaging for diagnosing OF.
