Jugulare Tumors (jugulare + tumor)
Kinds of Jugulare Tumors Selected AbstractsAngiomatous type of jugular foramen meningioma with neck extension: Differential diagnosis from paraganglioma and schwannomaHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 8 2007Zeng-Chang Chen MD Abstract Background. Meningiomas involving the jugular foramen and parapharyngeal space are extremely rare. They most commonly occur intracranially and then extend to the extracranial region through the foramen of the skull base, such as jugular foramen. Clinically, these tumors mimic the more common glomus jugulare tumor. Preoperative diagnosis can be correct on the basis of the characteristic imaging findings. Methods. A 52-year-old woman was seen with a left neck mass and mixed-type hearing loss. She underwent physical examination, MRI, high-resolution CT, and angiography. Results. Physical examination revealed a retrotympanic, pulsatile red mass in the left ear, and mild bulging of the left oropharyngeal wall. The patient was found to have the spreading, carpet-like, meningioma with extracranial extensions via jugular foramen to parapharyngeal space. Preoperative imaging strategy allowing accurate preoperative diagnosis is discussed. Conclusions. Accurate distinction between meningioma and glomus tumor or schwannoma is possible in most cases, with attention to fine radiologic detail. © 2007 Wiley Periodicals, Inc.

Foote MD Abstract Background We evaluated toxicity and long-term efficacy of stereotactic radiosurgery in patients with symptomatic or progressive glomus jugulare tumors. Methods Twenty-five consecutive patients (age, 30,88 years; 17 women, 8 men) who underwent stereotactic radiosurgery with the Leksell Gamma Knife (dose, 12,18 Gy) were prospectively followed. MRI and clinical examinations were performed at 6 months and 1, 2, and 3 years, and then every 2 years. Results None of the tumors increased in size, 17 were stable, and 8 decreased (median imaging follow-up, 35 months; range, 10,113 months). Symptoms subsided in 15 patients (60%); vertigo occurred in 1, but balance improved with vestibular training (median clinical follow-up, 37 months; range, 11,118 months). No other new or progressive neuropathy of cranial nerves V,XII developed. Conclusions Stereotactic radiosurgery can achieve excellent tumor control with low risk of morbidity in the treatment of glomus jugulare tumors. The lower cranial nerves can safely tolerate a radiosurgical dose of 12 to 18 Gy. © 2002 Wiley Periodicals, Inc.

Hinerman MD Abstract Purpose To evaluate the results of treatment for 71 patients with 80 chemodectomas of the temporal bone, carotid body, or glomus vagale who were treated with radiation therapy (RT) alone (72 tumors in 71 patients) or subtotal resection and RT (8 tumors) at the University of Florida between 1968 and 1998. Methods and Materials Sixty-six lesions were previously untreated, whereas 14 had undergone prior treatment (surgery, 11 lesions; RT, 1 lesion; or both, 2 lesions) and were treated for locally recurrent disease. All three patients who received prior RT had been treated at other institutions. Patients had minimum follow-up times as follows: 2 years, 66 patients (93%); 5 years, 53 patients (75%); 10 years, 37 patients (52%); 15 years, 29 patients (41%); 20 years, 18 patients (25%); 25 years, 12 patients (17%); and 30 years, 4 patients (6%). Results There were five local recurrences at 2.6 years, 4.6 years, 5.3 years, 8.3 years, and 18.8 years, respectively. Four were in glomus jugulare tumors and one was a carotid body tumor. Two of the four patients with glomus jugulare failures were salvaged, one with stereotactic radiosurgery and one with surgery and postoperative RT at another institution. Two of the five recurrences had been treated previously at other institutions with RT and/or surgery. Treatment for a third recurrence was discontinued, against medical advice, before receiving the prescribed dose. There were, therefore, only 2 failures in 65 previously untreated lesions receiving the prescribed course of RT. The overall crude local control rate for all 80 lesions was 94%, with an ultimate local control rate of 96% after salvage treatment. The incidence of treatment-related complications was low. Conclusions Irradiation offers a high probability of tumor control with relatively minimal risks for patients with chemodectomas of the temporal bone and neck. There were no severe treatment complications. © 2001 John Wiley & Sons, Inc. Head Neck 23: 363,371, 2001. [source] Auditory Brainstem Response versus Magnetic Resonance Imaging for the Evaluation of Asymmetric Sensorineural Hearing Loss,THE LARYNGOSCOPE, Issue 10 2004Roberto A. Cueva MD Abstract Objectives/Hypothesis: Auditory brainstem response (ABR) testing and magnetic resonance imaging (MRI) are compared for the evaluation of patients with asymmetric sensorineural hearing loss (SNHL). MRI with gadolinium administration is the current gold standard for identifying retrocochlear lesions causing asymmetric SNHL. The study seeks to determine the sensitivity and specificity of ABR in screening for possible retrocochlear pathology. Most important among SNHL etiologies are neoplastic lesions such as vestibular schwannomas, cerebellopontine angle (CPA) tumors, as well as multiple sclerosis, stroke, or other rare nonneoplastic causes. The study results will allow the author to recommend a screening algorithm for patients with asymmetric SNHL. Study Design: The study is a multi-institutional, institutional review board approved, prospective, nonrandomized comparison of ABR and MRI for the evaluation of patients with asymmetric SNHL. Methods: Three hundred twelve patients (between the ages of 18 and 87) with asymmetric SNHL completed the study. Asymmetric SNHL was defined as 15 dB or greater asymmetry in two or more frequencies or 15% or more asymmetry in speech discrimination scores (SDS). These patients prospectively underwent both ABR and MRI. The ABR and MRI were interpreted independently in a blinded fashion. In addition to the ABR and MRI results, a variety of clinical and demographic data were collected. Results: Thirty-one (9.94%) patients of the study population of 312 were found on MRI to have lesions causing their SNHL. Of the 31 patients with causative lesions on MRI there were 24 vestibular schwannomas, 2 glomus jugulare tumors, 2 ectatic basilar arteries with brainstem compression, 1 petrous apex cholesterol granuloma, 1 case of possible demyelinating disease, and 1 parietal lobe mass. Twenty-two of the 31 patients had abnormal ABRs, whereas 9 patients (7 with small vestibular schwannomas) had normal ABRs. This gives an overall false-negative rate for ABR of 29%. The false-positive rate was found to be 76.84%. Sensitivity of ABR as a screening test was 71%, and specificity was 74%. Conclusions: Ten percent of patients with asymmetric SNHL (by this study's criteria) are likely to have causative lesions found on MRI. Although the recently reported annual incidence of vestibular schwannoma in the general population is 0.00124%, for patients with asymmetric SNHL in this study, the incidence was 7.7% (nearly 4 orders of magnitude higher). ABR has been demonstrated to have low sensitivity and specificity in the evaluation of these patients and cannot be relied on as a screening test for patients with asymmetric SNHL. Keeping the use of MRI conditional on the results of ABR will annually result in missed or delayed diagnosis of causative lesions in 29 patients per 1,000 screened. The author recommends abandoning ABR as a screening test for asymmetric SNHL and adoption of a focused MRI protocol as the screening test of choice (within certain guidelines). [source] |
