Abstract

Temporomandibular joint synovial cysts pose diagnostic challenges due to their rare occurrence and clinical resemblance to other cystic lesions. This study presents an 84-year-old male with a histopathologically confirmed synovial cyst in the temporomandibular joint. Clinical examination and magnetic resonance imaging delineated a homogeneous unilocular lesion with hyperintense on T1-weighted images and hyperintensity on T2-weighted and proton density images. Notably, the cyst demonstrated dynamic displacement within the mandibular fossa during mouth-opening. The aim of this study was to report the magnetic resonance imaging findings of a case presenting a temporomandibular joint synovial cyst and to provide a concise review of pertinent cases documented in the existing literature for comparative purposes.
