Osteoid osteoma of the eminence of the temporomandibular joint

We describe an osteoid osteoma in the articular eminence of the left temporomandibular joint of a 24-year-old woman. This is an uncommon tumour of the jaws, and has not previously been reported in this location. The mass was removed, she made a good recovery, and there are not signs of recurrence four years later.
