Abstract

Paragangliomas are highly vascular, slow growing neoplasms that can occur within the temporal bone, as well as other sites in the head and neck. Preoperative angiography showed no feeding artery of the tumor in our case, but Zellenballen and hypervasularity were observed histologically. Tympanic paragangliomas confined to the middle ear cavity do not need preoperative embolization.
