Computed tomography of jugulotympanic paragangliomas

Seven cases of jugulotympanic paragangliomas were studied with computed tomography (CT) and verified by angiography and surgery. All of five glomus jugulare tumors were detected and their extent accurately demonstrated by CT. Two small glomus tympanicum tumors were not convincingly demonstrated. Computed tomography is useful in investigating this neoplasm when it extends beyond the tympanic cavity or is associated with bone destruction.
