An ipsilateral trismus of jaw-closing muscles during jaw opening is reported in a patient with brain stem tuberculoma. This condition is only superficially simulated by spasticity or tetanus. The decisively differentiating clinical and electromyographic features and the possible pathophysiologic mechanism underlying such trismus are discussed.
