Abstract
A cavernous malformation (CM) with trigeminal neuralgia (TN) is relatively rare. We report a patient who presented with TN caused by a CM in the cerebellopontine angle. A 37-year-old man presented with a history of episodic, shock-like, right facial pain of 2 months' duration. Neurologic examination revealed diminished sensation in the distribution of the right trigeminal nerve. Magnetic resonance imaging showed an ipsilateral minimally enhancing lesion affecting the trigeminal nerve with characteristics of a CM and evidence of hemorrhage in the cerebellopontine angle. The patient underwent percutaneous balloon compression (PBC) of the Gasserian ganglion for trigeminal ganglia. The patient's pain improved significantly after completion of this microsurgical method. CMs can damage the trigeminal nerve and cause TN. PBC of the Gasserian ganglion can be undertaken safely and can relieve pain caused by TN caused by CM in the cerebellopontine angle.
