Popis: Clinical Presentation A double contour of the cortical border in the temporomandibular joints (TMJs) is a rare sign that can be seen in the mandibular condyles and/or in the glenoid cavity. This sign can be attributed to several causes and may have different clinical manifestations and management. Differential Diagnosis Subcortical erosion, incipient formation of subchondral cysts, and crescent sign were considered. Movement artifacts may sometimes create a false-positive sign. Diagnosis and Management Double contour of the TMJs can be better visualized on cone beam computed tomography. Because it is a nonspecific sign, it must be correlated with a complete medical history to be linked to a specific diagnosis. Discussion Double contour of the components of the TMJs can represent a sign of active pathosis and be a sign of bone remodeling in asymptomatic patients. Magnetic resonance imaging and clinical studies have shown a strong correlation between double contour and disk dislocation. It is important that the radiologist identify this sign and its clinical significance, with the purpose of helping the clinician in diagnosis and management.
