Treatment of Trigeminal Neuralgia With Stereotactic Radiosurgery Improved Symptoms of Morbihan Syndrome

Abstract

Trigeminal neuralgia (TN) is a neuropathic pain disorder characterized by paroxysmal pain in the maxillary and mandibular regions of the face. Morbihan syndrome is a disease that classically presents with dermatologic findings, including progressive facial edema and erythema. There are no previous reports of the onset of trigeminal neuralgia with Morbihan syndrome or previous reports describing improvement in symptoms of Morbihan syndrome with treatment of trigeminal neuralgia. We describe the case of a 62-yearold female who presented with trigeminal neuralgia and shortly thereafter developed significant facial edema and was diagnosed with Morbihan syndrome. The neuralgia was refractory to medical management and was effectively treated with stereotactic radiosurgery (SRS). This coincided with an improvement in her Morbihan syndrome that is now controlled following stereotactic radiosurgery and continued lymphatic massage.
