Intraoperative Monitoring of the Cochlear Nerve during Neurofibromatosis Type-2 Vestibular Schwannoma Surgery and Description of a “Test Intracochlear Electrode”
Conclusion Electrically evoked CN monitoring can provide objective evidence of CN function after VS excision and aid in the decision-making process of hearing rehabilitation in patients who will be rendered deaf.

Sporadic Hemangioblastoma of the Cavernous Sinus and Meckel's Cave
Conclusions We present an exceptional case of supratentorial HB without associated von Hippel–Lindau (VHL) disease, which was predominantly located in the cavernous sinus and Meckel's cave and led to multiple cranial nerve symptoms. We describe imaging characteristics and radiologic–pathologic correlation of this atypically located HB, which can be difficult to consider in the differential diagnosis presurgically.

Early Intracranial Aneurysm Recurrence after Microsurgical Clip Ligation: Case Report and Review of the Literature
J Neurol Surg Rep 2018; 79: e93-e97 DOI: 10.1055/s-0038-1676454Microsurgical clip ligation is considered a definitive treatment for intracranial aneurysms (IAs), resulting in low rates of local recurrence that range from 0.2 to 0.5% and a latency period that averages about a decade. Our case report describes an early asymptomatic recurrence (i.e., without sentinel headache or seizure) less than 1 year after this 20-year-old woman underwent clip ligation of a ruptured anterior communicating artery (AComA) aneurysm. At recurrence, the patient underwent coiling of the regrowth; follow-up imaging at 6 and 18 months demonstra...

Tension Pneumocephalus after Cervical Spine Surgery: A Case Report with Review of the Literature
J Neurol Surg Rep 2018; 79: e88-e92 DOI: 10.1055/s-0038-1676298This is the case of a 66-year-old male with cervical myelopathy secondary to severe cervical stenosis manifesting as worsening dexterity and numbness in his right hand. The patient underwent C3–C6 laminoplasty with bilateral foraminotomies. During the procedure an incidental durotomy occurred which was patched intraoperatively with Duragen and Tisseel. At 1 month follow-up, the patient reported that he was doing well and skin sutures were removed. Two days later, the patient presented to the emergency department with postoperative wound dehiscence, cerebros...

Chondrosarcoma in the Petrous Apex: Case Report and Review
Conclusion Expanded endoscopic endonasal transclival approach to petrous apex and reconstruction appears to be safe and feasible technique, capable of achieving total removal of identified lesions near the petrous apex. Nonetheless, future studies with a greater number of patients are crucial to confirm and consolidate this initial impression.

Giant Calvarial Ewing's Sarcoma: A Case Report
J Neurol Surg Rep 2018; 79: e79-e82 DOI: 10.1055/s-0038-1673626Ewing's sarcoma (EWS) is the second most common primary bone tumor seen in children and adolescents, first being osteosarcoma. Skull lesions are seen in 6 to 9% of cases. The tumor tends to reside most frequently on frontal and parietal bones. In the literature, majority of papers on calvarial EWS present cases with intracranial involvement; extracranial extension is reported in only eight cases. The case that we are presenting in this report is a 23-year-old male patient with multiple infiltrations in femur, costal bones, and calvarium which had been diagnosed...

Anterior Cranial Fossa Calcifying Pseudoneoplasm of the Neuroaxis —Diagnosis Using a Transblepharoplasty Approach
We present the case of an asymptomatic patient with an incidentally discovered right anterior cranial fossa mass with extension through the posterior and anterior table of the right frontal sinus and right superior orbital roof. Open biopsy was performed via a transblepharoplasty incision with pathological diagnosis of CAPNON. The biopsy approach was well hidden and resulted in minimal to no postoperative scarring and little postoperative pain. We present the first documented case of CAPNON involving the frontal sinus via the anterior cranial base. Given our experience, in a patient with a mass involving the frontal sinus ...

Surgical Treatment of a Rare Presentation of Bertolotti's Syndrome from Castellvi Type IV Lumbosacral Transitional Vertebra: Case Report and Review of the Literature
Conclusion Patients who present with symptoms consistent with Bertolotti's syndrome, even if they have a type III or type IV LSTV, should be considered for surgical treatment of their LSTV. These patients can respond well, even if symptoms have been present for years. Given the prevalence of these anatomic variants in the general population (10–12% in most series), Bertolotti's syndrome should be considered in the differential diagnosis of any patient with a presentation of L5 radiculopathy and/or back pain.

Surgery for Triple Pathology of Giant Vestibular Schwannoma Associated with Carotid Artery Stenosis and Intracranial Aneurysm: Case Report
J Neurol Surg Rep 2018; 79: e65-e69 DOI: 10.1055/s-0038-1666806Here we report the case of a 56-year-old woman who presented with a highly unusual combination of three pathologies, namely a giant left-sided vestibular schwannoma, severe stenosis of the left internal carotid artery, and a right anterior cerebral artery aneurysm. The chosen approach comprised three consecutive surgical procedures, namely (1) aneurysm embolization, (2) carotid stenosis stenting, and (3) vestibular schwannoma excision. This approach avoided complications and achieved a satisfactory functional outcome. To the best of our knowledge, this combinat...

Solitary Infiltrating Meningioma of the Trochlear Nerve: Case Report
We report the case of a solitary meningioma infiltrating the trochlear nerve, the first in a patient without a neurocutaneous disorder or cavernous sinus involvement. The patient presented with diplopia was found to have a focal enhancing mass encompassing the trochlear nerve. Following surgical resection, pathological examination showed meningioma infiltrating the nerve itself, demonstrated on the included pathology images. A review of the literature and discussion of meningiomas infiltrating cranial nerves are included.

Anterior Clinoid Metastasis Removed Extradurally: First Case Report
Conclusion This is the first case report of a metastasis of any kind on ACP. Metastasis should be included as a part of the differential diagnosis of lesions of the anterior clinoid. Extradural clinoidectomy is a safe and effective method in the treatment of these tumors.

Giant Cell Tumor of the Lateral Skull Base: Diagnostic and Management Options
J Neurol Surg Rep 2018; 79: e41-e54 DOI: 10.1055/s-0038-1645885Giant cell tumor of bone (GCTB) is a rare, benign, osteolytic neoplasm that most commonly occurs in early adulthood and often involves the long bones of the body. Although GCTB largely affects the epiphyses of long bones, several reports of GCTB involvement of the cranial and facial bones exist in the literature. In addition to reviewing other reported cases of GCTBs of the lateral skull base in the literature, the authors report here on the clinical presentation, radiographic findings, and neurosurgical management of a patient found to have a GCTB of the middl...

Pituitary Abscess: A Rare Clinical Entity in the Presence of Acute Rhinosinusitis: A Case Report
J Neurol Surg Rep 2018; 79: e36-e40 DOI: 10.1055/s-0038-1656531A pituitary abscess is an often-overlooked diagnosis in the clinical presentation of a sellar mass. Due to its rare incidence and nonspecific presentation, diagnosis and treatment is often delayed. The authors describe a 56-year-old male patient presenting with acute onset of severe headache, visual field deficit, and radiologic findings of an expansile sellar lesion. The presenting symptoms were unremarkable for the diagnosis of meningitis, cavernous sinus thrombosis, and septicemia. Recent medical history included symptoms of rhinosinusitis on the days preced...

Anterior Skull Base Reconstruction: Does Fat Preparation Matter?
Conclusions This study demonstrates that drying and compressing the fat graft improves autologous fat reconstruction success for anterior skull base defects, and does not add significantly to surgical time over nonprepared fat.

Hemangioma of the Cavernous Sinus: A Case Series
We describe the clinical presentations, imaging findings, and management of two male patients with CSHs. Case Report Case 1 describes a 57-year-old man who presented with vision changes and cranial nerve palsies. Initial imaging and surgical biopsy were nondiagnostic. Follow-up Tc-99m tagged red blood cell (RBC) imaging supported CSH diagnosis. He was treated with surgical resection and radiotherapy.Case 2 describes a 57-year-old man who presented with chronic headache. Imaging findings were suggestive of CSH. He underwent endoscopic endonasal surgical resection and a final diagnosis of CSH was made via biopsy. ...
