Magnetic Resonance Imaging Features of Progressive Condylar Resorption: A Case Report

Abstract

Progressive condylar resorption is a dysfunctional remodeling of the temporomandibular joint of unknown origin. It usually manifests in young girls and causes reduced ramus height, loss of condylar volume, steep mandibular angle, limited jaw motion, and pain. On magnetic resonance imaging, the condition is associated with anterior disc displacement with or without reduction. This article discusses imaging features of progressive condylar resorption that cause severe temporomandibular joint degenerative changes, emphasizing the careful evaluation of imaging changes of the temporomandibular joint in young female patients. The early diagnosis of progressive condylar resorption helps to reduce the further progression of the condition.
