Structural anomalies of the jugular foramen (JF) and adjacent structures may contribute to development of pulsatile tinnitus (PT). The goal of this study was to assess anatomical variants in the ipsilateral JF region in patients with PT and to explore possible predisposing factors for PT. One hundred ninety-five patients with PT who underwent CT angiography and venography of the temporal bone were retrospectively analyzed. Anatomic variants including dominance of the ipsilateral JF, bony deficiency of the sigmoid sinus and internal carotid artery canal, high riding or dehiscent jugular bulb, dehiscence of the superior semicircular canal, tumors in the JF region, or cerebellopontine angle were assessed. Of 195 patients with PT, the prevalence of a dominant JF on the ipsilateral side of patients with PT was 67.2%. Furthermore, the dominant JF demonstrated a significant correlation with the presence of ipsilateral PT ( < 0.001). No anatomical variants were present in 22 patients (11.3%), whereas in patients with structural variants, bony deficiency of the sigmoid sinus was most common (65.6%), followed by high riding (54.9%) or dehiscent jugular bulb (14.4%). Dehiscent internal carotid artery canal (3.1%) and superior semicircular canal (4.1%) were occasionally identified, while arteriovenous fistula, arterial aneurysm and tumors arising from the JF region or cerebellopontine angle were rarely encountered. Structural abnormalities of the JF and adjacent structures may predispose to the development of PT. Knowledge of these anatomical variants in the JF region may help establish a clinical strategy for addressing PT.

Jugular foramen schwannomas are rare. To our knowledge only a small number of series including a large number of patients have been reported. We aimed to analyse the clinical characteristics, surgical approaches, and outcome of patients undergoing treatment for jugular foramen schwannomas via a retrospective analysis of departmental records. Data for 28 patients treated for jugular foramen schwannomas in the Department of Neurosurgery at our tertiary level referral institution between January 2001 and December 2010 were analysed. Most patients were in the fourth decade of life, with the duration of symptoms ranging from 1 month to 13 years. A skull base approach was used in every surgically treated patient. Of the 19 patients for whom radiological follow-up were available, complete tumor excision was achieved in 17 patients. Follow-up ranged from 3 months to 59 months (mean, 32 months). One patient died and three had permanent morbidity in the form of facial nerve palsy. Jugular foramen schwannomas are best treated by total surgical resection. Partial resection is appropriate for tumors with adhesions to the brainstem and in medically unfit patients. Subsequent radiosurgery can be used for small residual tumors.

Review
The goal in paraganglioma resection is to allow adequate exposure to remove the lesion while preserving cranial nerve function. Knowledge of the anatomy of the jugular foramen is crucial to this endeavor. In this report the authors describe a jugular foramen approach for the resection of glomus jugulare tumors in cases in which rerouting of the facial nerve can be avoided. This approach provides adequate exposure of the jugular bulb for many jugulotympanic paragangliomas without increased risk of injury to the facial nerve. In addition, special circumstances surrounding intracranial and carotid artery involvement are briefly discussed.

Chordoid meningioma (CM) is a rare histological variant of meningioma and is classified as an atypical meningioma on pattern alone. Herein is described the first case of CM occurring in the jugular foramen. The patient was a 45-year-old woman with a 2 year history of progressive right hearing loss. Magnetic resonance imaging (MRI) demonstrated a large, dumbbell-shaped, homogenously gadolinium-enhanced mass in the right jugular foramen, extending medially to the cerebellopontine angle and caudally into the upper carotid space. Angiographic findings supported a diagnosis of schwannoma. Intraoperatively, the tumor appeared to involve the right glossopharyngeal nerve completely and the vagus nerve incompletely, and was incompletely resected. Microscopically, the tumor consisted predominantly of cords and nests of medium-sized cells with bland cytological features, surrounded by a pale basophilic mucin. Immunohistochemically, the tumor cells demonstrated reactivity for epithelial membrane antigen (membranous) and vimentin, with negative staining for S-100 protein, cytokeratin, CD34, glial fibrillary acidic protein (GFAP), synaptophysin, and chromogranin A. Based on the chordoid histology, an organoid lobular arrangement of the tumor cells, and the location of the tumor (jugular foramen), the differential diagnosis included not only a chordoma but also a paraganglioma (glomus jugulare tumor). Histological identification of typical meningotheliomatous areas, plus selective immunohistochemical panel, is important to establish the correct diagnosis.

Three patients with neurinomas of the jugular foramen are described. One of them had a small tumor confined within the jugular foramen and each of the other two had a tumor originating from the glossopharyngeal nerve. The common feature in all these patients was the presence of marked enlargement of the jugular foramen. Polytomography, jugular venography and bilateral retrograde vertebral arteriography were used to make the diagnosis. Total removal of their tumors was successfully accomplished using microsurgical technique. Forty-two other cases in the world literature are reviewed and analyzed.

Despite being pathologically benign, jugular foramen meningioma (JFM) may be locally aggressive and spread in three compartments. Because of the complex anatomical location, radical removal of JFM usually causes serious morbidity through lower cranial nerve (LCN) deficits. To accomplish long-standing tumor control with good functional outcomes, we report function-preserving multimodal treatment (FMT) for JFM, comprising the combination of intradural tumor removal with the preservation of LCN function and stereotactic radiosurgery (RS) for the residual tumor. This study investigated six JFM patients (five women, one man). Preoperatively, five patients showed no LCN sign. All patients underwent function-preserving retrosigmoid intradural tumor removal, and no patient developed new LCN deficit. Three patients underwent RS for the residual tumor at 8 to 12 months after surgery. After RS, all three tumors were controlled. No patients showed tumor recurrence or new LCN deficits in the follow-up period (2 months to 8 years). FMT for JFMs can accomplish long-standing tumor control with excellent functional outcomes.

OBJECTIVE
This report describes a case of a spontaneous cerebrospinal fluid leak at the jugular foramen that was surgically repaired via the infralabyrinthine approach with adjunct use of intrathecal fluorescein and stereotactic navigation.
PATIENTS
A 39-year-old woman presenting with clear otorrhea confirmed to be cerebrospinal fluid (CSF) emanating from a defect in the jugular foramen.
INTERVENTION
Surgical repair of the skull base defect using an infralabyrinthine approach to the jugular foramen. During surgery, intrathecal fluorescein and stereotactic navigation were used to localize the defect and confirm a successful repair.
MAIN OUTCOME MEASURE
Recurrence of a CSF leak.
RESULTS
The defect was successfully repaired using the techniques described, resulting in cessation of the patient's CSF leak. There was no recurrence of the CSF leak up to a 4-month postoperative outpatient follow-up.
CONCLUSIONS
Diagnosis and repair of spontaneous otogenic CSF leaks in an uncommon location like the jugular foramen are challenging. This report demonstrates the successful use of the infralabyrinthine approach for control of a CSF from the jugular foramen. In addition, use of techniques, such as intrathecal fluorescein and stereotactic navigation that are not routinely used in otology and neurotology allowed for safe, effective repair of the leak in this case.

OBJECTIVE
To examine the microsurgical anatomy of the jugular foramen and correlate anatomical findings to clinical manifestations of jugular foramen schwannomas concerning tumor origin and location.
STUDY DESIGN
Anatomical analysis of jugular foramen was performed by dissection of 25 cadavers (50 sides). By retrospective review of 9 cases of jugular foramen schwannomas surgically treated, the origin and location of tumor were studied.
SETTING
Tertiary referral center.
MAIN OUTCOME MEASURES
The anatomical characteristics of jugular foramen, lower cranial nerves, and inferior petrosal sinus were correlated with the origin and growth pattern of jugular foramen schwannomas.
RESULTS
The superior and inferior ganglions of the glossopharyngeal nerve and the superior ganglion of the vagus nerve were located within the jugular foramen. The superior ganglions of the glossopharyngeal and vagus nerves were located superiorly, whereas the inferior ganglion of the glossopharyngeal nerve was found inferiorly in relation to the inferior petrosal sinus orifice. In our series of 9 cases of jugular foramen schwannoma, the most common nerve of origin was the vagus nerve, followed by the glossopharyngeal nerve.
CONCLUSION
The reason for the predilection of the jugular foramen schwannoma for the glossopharyngeal and vagus nerves may be associated with the presence of their ganglions within the jugular foramen. Also, the inferior petrosal sinus may act as a barrier to tumor growth, and the location of the ganglion of tumor origination within the jugular foramen in relation to the inferior petrosal sinus may be correlated to the predominant direction of tumor extension.
