In this pictorial review, an introductory paragraph emphasizes the significance of some anatomical aspects for optimal imaging of the temporomandibular joint (TMJ). The most frequent pathologies: internal derangement (ID) and osteoarthritis (OA) are comprehensively discussed and illustrated. Less common conditions: ID and OA-like changes in children and adolescents, idiopathic condylar resorption, inflammatory arthritis, and juvenile idiopathic arthritis are briefly discussed. A short paragraph on differential diagnostics in young patients is included followed by a brief comment on expansile lesions that occasionally may occur in the TMJ.
Keywords: TMJ differential diagnostics in young patients; TMJ disorders; anatomy; expansile TMJ lesions; idiopathic condylar resorption; inflammatory arthritis; internal derangements; juvenile idiopathic arthritis; osteoarthritis.
