Surgical resection of jugular foramen tumors poses a significant challenge to skull base surgeons with the selection of an appropriate surgical approach, a matter of some debate. Jugular foramen metastatic tumors may mimic paragangliomas, and in some selected cases surgical resection is needed. In this video, we demonstrate the microsurgical gross total resection of a jugular foramen tumor via a postauricular trans-jugular trans-sigmoid approach. The patient is a 61-year-old man with a 7-year history of medullary thyroid cancer, who underwent three neck operations and radiation to the neck. He developed lower cranial nerve palsies (IX, X, and XI) with preoperative aspiration deficits, dysphonia, status post phonosurgery for vocal cord paralysis, profound sensorineural hearing loss, and muscle atrophy of the left shoulder. He initially received stereotactic radiation of the jugular foramen tumor at an outside hospital without histopathological diagnosis. Follow-up magnetic resonance images (MRIs) showed progressive enlargement of the tumor over the postradiation year. The decision was made to resect this tumor to enable histopathological diagnosis, and to provide local tumor control, since his primary disease has been stable. He underwent microsurgical gross total resection via a transjugular transsigmoid approach. After skeletonizing the sigmoid sinus and jugular bulb, the sigmoid sinus was ligated and rolled toward the jugular bulb, where the major part of the tumor was. Then, using the transjugular route, the tumor was removed en bloc. The surgery and postoperative course were uneventful. The histopathology was a thyroid medullary cancer metastasis. He was followed with serial MRIs, and there was no recurrent tumor at 2 years follow-up. In this video, microsurgical techniques and important steps for the resection of a jugular foramen metastatic tumor are demonstrated.The link to the video can be found at: https://youtu.be/oXC6fX2CC84.

Abstract The complex anatomical structure of jugular foramen (JF) makes a challenge for the diagnose and treatment of this region’s tumors. The purpose of the study was to investigate the effect of surgical resection in patients with JF tumors. A total of 77 patients with JF tumors treated with surgical resection between 2012 and 2021 were retrospectively reviewed. General characteristics, tumor classification, surgical approach and outcomes were retrospectively analyzed. The mean follow-up period was 4.5 years (ranging 0.5-8.5 years). Of the enrolled patients, 63 patients (81.82%) were diagnosed with JF schwannomas. 67 cases (87.01%) of the total patients received gross-total resection. Preoperatively, hoarseness and/or dysarthria served as the most complained symptoms (n=41, 53.25%), followed by swallowing disturbance (n = 37, 48.05%), hearing disturbance and/or tinnitus (n = 32, 41.56%). Postoperatively, a total of 52 patients (67.53%) were without significant symptoms. Worsened hoarseness and/or dysarthria symptoms were found in 14 patients (18.18%). Besides, 6 cases (7.79%) of the enrolled patients showed worsened swallowing disturbance. 8 patients (10.39%) presented with facial palsy after operation and 3 of them got improvement during the follow-up. Nine patients (12.68%) had tumor recurrence and there was one death (1.3%) associated with surgery during the perioperative period in the cohort. Therefore, surgical resection was an effective treatment of JF tumors with improvements of symptoms and good control of tumor. However, operation on this region was at the risks of worsening cranial nerve deficits and death, which needed advance in skull base surgery and rich experience.

Jugular foramen tumors are rare skull base tumors having complex neurovascular anatomy. Most common being paragangliomas, lower cranial nerve schwannomas and meningiomas. Being the conduit for important neuro-vascular structures, potential complications following surgery are a frequent source of morbidity. Retrospective study done from March 2008 to September 2014. All patients underwent highresolution computer tomography (HRCT) of temporal bones and magnetic resonance imaging (MRI) with angiography in pre-operative period. Surgical approach and pre-operative endovascular intervention depended on the site and extent of the lesion. Extent of tumor removal was determined at the time of surgery. Patients with incomplete excisions in postoperative imaging were subjected to radiotherapy depending on histo-pathological diagnosis. Total of 22 patients of jugular foramen lesion were operated. Histopathological diagnosis included paraganglioma(n=18), schwannomas(n=2), p l a s m a c y t o m a ( n = 1 ) , s q u a m o u s c e l l carcinoma(n=1). Eighth cranial nerve was the most common involved nerve preoperatively (100%). Infratemporal Fossa approach, along with its modication, and conservative jugulopetrosectomy approach were used for surgical excision as per the extent of tumor. Complete excision was done in 73% (n=16), and postoperative radiotherapy was given to rest of the patients. The most common postoperative complication was lower cranial nerve decit in immediate post op period(n=15, 68%) (new onset n= 3, 13% and n=12, 55% had preoperative paresis), on follow up lower cranial nerve palsy improved in 50% in follow up (n=7). Most common tumor of the jugular foramen was paraganglioma followed by lower cranial nerve schwannoma. Surgical management depends on the extent of tumor. Multidisciplinary approach provides better patient outcome. Histopathological diagnosis aids to give targeted radiotherapy to the local site, and hence surgical excision of JFT(Jugular foramen tumor) is recommended.

Abstract BACKGROUND: Intramedullary spinal ependymomas are rare tumors. OBJECTIVE: To provide a large retrospective review in the modern neuroimaging era from a tertiary center where aggressive surgical resection is favored. METHODS: Charts of intramedullary spinal ependymomas treated between 1983 and 2006 were reviewed. RESULTS: Sixty-seven cases were reviewed. The mean age was 45.6 years (range, 11-78 years) with a male-to-female ratio of 2:1. The most common location was the cervical spine, followed by the thoracic and lumbar spine. The average duration of symptoms was 33 months, with the most common symptom being pain and/or dysesthesias, followed by weakness, numbness, and urinary or sexual symptoms. Gross total resection was achieved in 55 patients and a subtotal resection was performed in 12 patients; 9 patients were treated with adjuvant radiation therapy. Mean follow-up was 32 months. The mean McCormick neurological grade at last follow-up was 2.0. The preoperative outcome correlated significantly with postoperative outcome (P < .001). A significant number of patients who initially worsened improved at their 3-month follow-up examination. Outcomes were significantly worse in patients undergoing subtotal resection with or without radiation therapy (P < .05). There were 3 recurrences. The overall complication rate was 34%. The primary complications were wound infections or cerebrospinal fluid leaks. CONCLUSION: Spinal cord ependymomas are difficult lesions to treat. Aggressive surgical resection is associated with a high overall complication rate. However, when gross total resection can be achieved, overall outcomes are excellent and the recurrence rate is low.

Abstract Objective Choroid plexus tumors (CPTs) are rare pediatric intracranial neoplasms, and mostly occur in the lateral ventricle. CPTs located in the infratentorial location are considered to be rare in the pediatric population. We present a series of eight patients treated in the last decade at our institution focusing on clinical presentations and their outcome after excision. Methods We performed an institutional retrospective review of patients who underwent surgical resection of infratentorial CPTs during the period from 2008 to 2017. Patients’ charts were reviewed for demographic data, clinical presentation, surgical treatment, and follow-up. Results There were eight patients (6 females and 2 males), with mean age for the cohort at presentation was 9.0 years. They represent 75% of 12 CPTs of all locations treated at the same period in our institution. These 8 infratentorial CPTs were in the fourth ventricle in seven, and in the cerebellopontine angle (CPA) in one. Seven patients had choroid plexus papillomas (WHO grade I) and 1 had an atypical choroid plexus papilloma (WHO grade II). Gross total resection was attempted in all patients. However, two of 3 patients with fourth ventricle floor invasion had subtotal resection with a thin layer of tumor left on the floor. The remaining 6 had a gross total resection. Six patients with preoperative hydrocephalus had a perioperative external ventricular drainage but none required permanent shunting after tumor resection. None showed recurrence/tumor progression without adjuvant therapy during the follow-up period of 20 months to 11 years. Conclusion Infratentorial dominance among pediatric CPTs in this series contradicts previous reports. Infratentorial CPTs are amenable to surgical resection. Unresected small residuals due to invasion to the fourth ventricle floor showed no regrowth during 2 to 3 years follow-up without adjuvant therapy. However, these patients with incomplete resection need watchful observations.

✓The authors present a case of clear cell sarcoma (CCS) in which the tumor originated in the S-1 nerve root and had been previously diagnosed as psammomatous melanotic schwannoma (PMS). This is the third case of a spinal nerve root origin for CCS reported in the English-language literature. The similar histogenesis of CCS and malignant melanoma supports the hypothesis that biological agents or immunotherapy are potentially important areas of investigation. The patient underwent S1–3 laminectomy and gross-total resection of the mass lesion. The border of the resection was extended 1 cm distal to the tumor margin. The postoperative period was uneventful. The new histopathological diagnosis was CCS (malignant melanoma of soft tissue). Despite total resection, the patient returned with disseminated disease at the 18-month follow-up visit. His follow-up magnetic resonance image of the lumbar spine revealed sacral L5–S3 involvement of the vertebral bodies along with disseminated cauda equina seeding. A CCS originating from peripheral nerves is quite rare. The histopathological and immunohistochemical appearance of CCSs resembles those of PMSs. Surgery should be the first choice of treatment.

Abstract BACKGROUND: Nonvestibular schwannomas are uncommon tumors of the brain often treated by surgical resection. Surgery may be associated with high morbidity. OBJECTIVE: We present a series of nonvestibular schwannomas treated with linear accelerator radiosurgery during a 19-year period. METHODS: This is a retrospective analysis of patients who underwent treatment of nonvestibular schwannomas at the University of Florida with linear accelerator radiosurgery between August 1989 and February 2008. Forty-nine patients underwent treatment during the study period, and 6 were lost to follow up. The mean age was 51 years (range, 17-82 years), 39% had previous surgical resection, and 67% presented with preradiosurgery cranial nerve deficits. There were 25 trigeminal, 18 jugular foramen, 2 facial, 2 oculomotor, 1 hypoglossal, and 1 high cervical schwannomas. The median tumor volume was 5.3 mL (range, 0.3-24.5 mL), treated with a median dose of 1250 cGy (range, 1000-1500 cGy). Study endpoints were actuarial local tumor control and neurological outcome. RESULTS: Forty-three patients were available for a median follow-up of 37 months (range, 6-210 months). Actuarial local tumor control was 97% at 1 year, 91% at 4.5 years, and 83% at 5 years. There were 4 new cranial nerve deficits (9%) including facial numbness (2 patients), anesthesia dolorosa (1 patient), and facial weakness (1 patient). Thirty-nine percent had documented clinical and/or symptomatic improvement. There were no other morbidity and no mortality with treatment. CONCLUSION: Radiosurgery for nonvestibular schwannomas offers good actuarial local tumor control and has superior morbidity compared with surgical resection. This is the largest linear accelerator radiosurgical series, and the second largest radiosurgical series reported to date.

Abstract Background Thymic carcinoma has been classified into 12 subtypes, thymic lymphoepithelioma-like carcinoma (LELC) is a type of them, and has a pathological organization similar to that of lymphoepithelioma, an undifferentiated type of nasopharyngeal carcinoma. According to a report from the International Thymic Malignancy Interest Group (ITMIG), thymic LELC is a rare tumor and accounts for 6% of all thymic carcinoma cases. We report two cases of surgical resection for thymic LELC and perform a search of other reports of thymic LELC, and clinical manifestations and follow-up data thus obtained are summarized. Case presentation Two patients underwent surgical resection for thymic LELC. In both, tumors were detected in the anterior mediastinum and a total thymectomy was performed. Each was diagnosed with thymic LELC and classified in accordance with the Masaoka staging system as modified stage II. In recent examinations, one patient was doing well after undergoing total resection, whereas early recurrence of distant lymph node metastasis was noted in the other at 5 months after the total resection procedure and died thereafter from a different disease. Conclusion We report two cases of surgical resection for thymic LELC. A successful total resection may positively affect prognosis: thus, long-term follow-up examinations must be performed.

Meningiomas are the second most common neoplasm in the cerebellopontine angle (CPA), and are challenging lesions to treat surgically. With significant refinements in surgical techniques, operative morbidity, and mortality have been substantially reduced. Total or near-total surgical resection can be accomplished in the majority of cases via appropriately selected approaches, and with acceptable morbidity. In this video, we present a 51-year-old woman, who had a 2-year history of vertigo with symptoms that progressed over time. She presented with blurry vision, sensorineural hearing loss, tinnitus, left-sided facial numbness, and double vision. Magnetic resonance imaging (MRI) showed a left-sided homogeneously enhancing mass at CPA with a supratentorial extension. MRI appearance was consistent with a CPA meningioma with supratentorial extension. The patient underwent surgical resection via a retrosigmoid approach. Suprameatal drilling and tentorial sectioning were necessary to achieve gross total resection. The surgery and postoperative course were uneventful. The histopathology was a WHO (world health organization) grade I meningioma. MRI showed gross total resection of the tumor. After a 1.5-year follow-up, the patient is continuing to do well with no residual or recurrent disease. In this video, microsurgical techniques and important steps for the resection of this challenging meningioma of the cerebellopontine angle are demonstrated.The link to the video can be found at: https://youtu.be/CDto52GxrG4.

Meningiomas represent the most common benign intracranial neoplasm in adults, with a considerably lower incidence in children. The authors present the case of an intracranial meningioma with invasion of, and intraluminal extension into, the transverse and sigmoid sinuses, jugular bulb, and internal jugular vein, resulting in venous occlusion in a 14-year-old girl. Computed tomography scanning, MR imaging, and conventional angiography were performed preoperatively. The patient underwent a 2-stage resection: the supratentorial component was resected first, and the infratentorial and venous sinus and jugular vein components were subsequently removed using a combined skull base approach. Gross-total resection was achieved by opening the lateral dural sinus and removing the meningioma from within the transverse and sigmoid sinuses, the jugular bulb, and the internal jugular vein. The patient remained neurologically intact after the staged tumor resections. Postoperative imaging confirmed the gross-total resection. This case illustrates the unusual property of an intracranial meningioma to invade the intrasinusoidal space and extend into the jugular vein without adherence to the underlying venous endothelium of the jugular vein.

Abstract Purpose: This study aimed to assess the clinical outcomes of salvage surgical resection (SSR) after stereotactic radiosurgery and fractionated stereotactic radiotherapy (SRS/fSRT) for brain metastasis.Methods: Between November 2009 and December 2018, we treated 427 consecutive patients with 919 lesions with SRS/fSRT for newly diagnosed brain metastasis at our hospital. During the follow-up period, we treated 19 consecutive patients who underwent 21 SSRs for recurrence, radiation necrosis (RN), and cyst formation after SRS/fSRT for newly diagnosed brain metastasis. Two patients underwent multiple surgical resections. Brain metastasis originated from the lung (n=15, 78.9%), breast (n=3, 15.7%), and colon (n=1, 5.2%). Results: The median time from initial SRS/fSRT to SSR was 14 months (range: 2–96 months). The median follow-up after SSR was 15 months (range: 2–76 months). The range of tumor volume at initial SRS/SRT was 0.121–21.459 cm3 (median: 2.188 cm3). Histopathological diagnosis after SSR was recurrence, RN and cyst formation in 13 and 6 cases, respectively. The median survival time from SSR and from initial SRS/SRT was 17 months and 74 months, respectively. The cases with recurrence had a significantly shorter survival time than those without recurrence (p=0.0453).Conclusion: The patients treated with SRS/fSRT for brain metastasis need long-term follow-up. SSR is a safe and effective treatment for the recurrence, RN, and cyst formation after SRS/fSRT for brain metastasis.
