primary Jugular Foramen meningioma imaging appearance and differentiating features
American Journal of Roentgenology, 2004Co-Authors: Andre J. Macdonald, Karen L. Salzman, Erik Gilbert, Ric H Harnsberger, Clough SheltonAbstract:Objective Primary Jugular Foramen meningiomas behave differently from meningiomas arising elsewhere. The differences have important clinical, imaging, and surgical implications. We reviewed the imaging appearances of primary Jugular Foramen meningiomas and evaluated them for features that might assist in differentiating them from other common Jugular Foramen lesions. Materials and methods A retrospective review identified five cases of primary Jugular Foramen meningioma. We defined it as primary when it was centered in the Jugular Foramen and secondary when it was centered in the posterior fossa with secondary extension into the Jugular Foramen. Secondary Jugular Foramen meningiomas were excluded from this study. Eight cases of Jugular Foramen paraganglioma and 10 cases of Jugular Foramen schwannoma were reviewed for comparison. Results Primary meningioma was characterized by centrifugal infiltration surrounding the skull base (5/5), a permeative-sclerotic appearance to the bone margins of the Jugular Foramen (5/5), and prominent dural tails (5/5). Flow voids were absent in all cases. Paraganglioma showed localized skull base infiltration, with predominant superolateral spread into the middle ear cavity (8/8). Flow voids and permeative destruction of the bone margins of the Jugular Foramen were typical. Schwannoma caused expansion of the Jugular Foramen with scalloped well-corticate bone margins, without skull base infiltration. Conclusion Primary Jugular Foramen meningioma is characterized by extensive skull base infiltration. A centrifugal pattern of spread, a permeative-sclerotic appearance of the bone margins of the Jugular Foramen, the presence of dural tails, and an absence of flow voids are particularly important features that assist in differentiating primary Jugular Foramen meningioma other more common Jugular Foramen lesions.

microsurgical management of Jugular Foramen schwannomas
Neurosurgery, 2013Co-Authors: Cara L. Sedney, Yoichi Nonaka, Ketan R. Bulsara, Takanori FukushimaAbstract:BACKGROUND Jugular Foramen schwannomas are uncommon and surgically challenging lesions. OBJECTIVE To determine the importance of surgical technique on morbidity and recurrence of Jugular Foramen schwannomas. METHODS A retrospective review and case-control analysis of a single-senior-surgeon series of 81 patients with surgically treated Jugular Foramen schwannomas was performed, focusing on operative technique. Patients undergoing an aggressive, total tumor resection (series 1) were compared with those undergoing more conservative resection focusing on preserving the pars nervosa (series 2). RESULTS There was a statistically significant (P = .04) decrease in permanent deficits of the cranial nerve 9/10 complex with a conservative technique. Recurrence was seen in 3 patients (5.7%) in series 1 and in 3 patients (10.7%) in series 2 (P = .36). Recurrence was treated with reoperation in 1 patient, radiation in 1 patient, and observation in the others. CONCLUSION Although radical gross total resection is desirable, it is not optimal for cranial nerve preservation in patients with Jugular Foramen schwannomas. A more conservative approach resulted in a statistically significant decrease in lower cranial nerve deficits. There was a nonstatistically significant trend toward increasing recurrence, which may be treated with multiple modality therapy in the modern era.
