All of the following are true about glomus-jugulare tumor except:

Glomus jugulare tumors are rare, slow-growing, hypervascular tumors that arise within the jugular foramen of the temporal bone. They are included in a group of tumors referred to as paragangliomas, which occur at various sites and include carotid body, glomus vagale, and glomus tympanicum tumors Glomus jugulare tumors occur predominantly in women in the fifth and sixth decades of life. Because of the insidious onset of symptoms, these tumors often go unnoticed, and delay in diagnosis is frequent. The most common symptoms are conductive hearing loss and pulsatile tinnitus. Other aural signs and symptoms are ear fullness, otorrhea, hemorrhage, bruit, and the presence of a middle ear mass. Significant ear pain is uncommon.
