Intraosseous Lesion in Mandibular Condyle Mimicking Temporomandibular Disorders: Report of 3 Cases

Pain and dysfunction in the temporomandibular joint (TMJ) region represent a diagnostic challenge. Temporomandibular disorders (TMD) are usually diagnosed by means of a thorough patient history and comprehensive clinical examination. However, additional diagnostic tests, such as imaging of the TMJ area, are necessary in cases where the signs do not explain the symptoms. Neoplasms and pseudotumors of the TMJ are quite uncommon, but their early recognition is necessary in order prevent the delay of correct treatment. This report describes 3 cases of different intraosseous lesions of the mandibular condyle in which the patient was erroneously first treated for a TMD.
