Targeted palliative endovascular embolization of a glomus jugulotympanicum tumor for refractory Jacobson's neuralgia: A case report.

Background: Glomus tumors around the jugular foramen and inner ear can have variable presentations, including lower cranial nerve palsies, tinnitus, hearing loss, or palpable neck mass. In general, these tumors are benign paragangliomas with the definitive treatment consisting of radiosurgery or surgery. Endovascular embolization can be added as a critical adjunctive therapy to reduce the tumor vascularity before surgical resection.
