Facial pain and muscle atrophy secondary to an intracranial tumour.

Orofacial pain rarely arises from a distant site. It is unusual for orofacial pain to be associated with wasting of the facial musculature and diminished sensation. This case report describes a patient who presented with temporomandibular joint pain dysfunction syndrome which was initially successfully managed with splint therapy. She re-presented later with unilateral wasting of the muscles of mastication, facial pain and diminished sensation ipsilaterally. An intracranial meningioma was diagnosed following an extensive series of investigations.
