Abstract

We present a case of a 58-year old man with a gradually enlarging right cheek mass. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a tumour with a chondroid matrix closely related to the temporomandibular joint. Subsequent surgical resection revealed a chondroblastoma-like chondroma. Identification of the the typical features of a chondroid matrix may aid in narrowing the differential diagnoses. Nonetheless, surgical resection is usually required to establish the definitive diagnosis.

Contrast-enhanced CT (venous phase, bone window) shows a connection between the mass and the right temporal bone via a small bony stalk (arrow) anterior to the articular tubercle of the right temporomandibular joint (*).
