Temporomandibular disorders can usually be diagnosed on the
basis of a thorough history and a comprehensive examination of
the patient. Additional diagnostic tests, such as imaging of the temporomandibular
joint (TMJ) area, are mandatory and must be
flawless in case of atypical findings. The aim of this report is to
illustrate pitfalls in clinical reasoning and in imaging procedures in
the diagnosis of temporomandibular pain and dysfunction. A case
report of a patient with osteocartilaginous exostosis of the
mandibular condyle, which was erroneously diagnosed and treated
as an internal derangement of the TMJ for half a year, is presented.
