Steven P Rowe, Elliot K Fishman
Three-dimensional (3D) methods for visualizing volumetric computed tomography (CT) data can aid in understanding the extent of a disease process and planning necessary surgical interventions. Recently, a new method of 3D image creation, known as cinematic rendering (CR), has been developed; it produces photorealistic images from standard CT acquisitions. We describe the CT appearance of a rare tumor type, odontogenic myxofibroma, in the mandible of a 33-year-old woman, and we focus on the potential applications of CR visualizations in this and similar scenarios...

OBJECTIVE: Our previous study of patients with unilateral temporomandibular joint (TMJ) osteoarthritis (OA) showed that the affected joints had greater horizontal condylar angle (HCA) compared with the contralateral unaffected joints. However, it was unclear whether the HCA changes preceded or were the result of OA changes. The aim of this longitudinal study was to investigate the relationship between HCA and OA progression. STUDY DESIGN: In total, 127 patients (with or without TMJ disorders) completed baseline and follow-up examinations (average time to follow-up 7...

Epithelioid osteoblastoma is a clinically aggressive subtype of osteoblastoma that favors the mandible and the maxilla. Its histologic features lie on a spectrum between conventional osteoblastoma and low-grade osteosarcoma, thus making it difficult at times to confirm the diagnosis. It is known to have a high risk of recurrence after surgical resection, but it is a benign entity and does not have the propensity to metastasize. To our knowledge, there are no published reports on findings of epithelioid osteoblastoma on positron emission tomography/computed tomography (PET/CT)...

REVIEW
Rebecca King, Nikki Tanna, Vinod Patel
The link between medication-related osteonecrosis of the jaw (MRONJ) and bone modulating drugs, such as bisphosphonates and denosumab, is well established, and the number of reported cases is increasing. The development of novel medications used in the treatment of cancer, as well as autoimmune and bone conditions, has led to more cases of MRONJ being reported. However, in addition to this group of medications, increasing numbers of new agents in cancer therapy, such as antiangiogenic agents, have also been implicated in the development of MRONJ...

OBJECTIVE: Salivary gland anlage tumor (SGAT), previously described as a squamous proliferative lesion or "congenital pleomorphic adenoma," is a rare, benign entity that presents within the first months of life. It occurs almost exclusively in the nasopharynx or posterior nasal cavity and demonstrates a biphasic composition of epithelial and mesenchymal elements. Although the clinical and histologic features of SGAT are well described, its etiology remains poorly understood...
