Aggressive condylar resorption.

This article describes the clinical and radiographic findings in a patient with unilateral aggressive condylar resorption that was diagnosed as osteoarthritis. We present a comprehensive documentation of the clinical manifestations, the appearance on conventional and advanced imaging, and the histopathologic findings. We discuss the systematic approach to develop a differential diagnosis, with specific emphasis on osteoarthritis and idiopathic condylar resorption. Finally, we also discuss the factors that play a role in management of this condition.
