Abstract
Downbeat nystagmus (DBN) is a neuro-otological finding frequently encountered by clinicians dealing with patients with vertigo. Since DBN is a finding that should be understood because of central vestibular dysfunction, it is necessary to know how to frame it promptly to suggest the correct diagnostic-therapeutic pathway to the patient. As knowledge of its pathophysiology has progressed, the importance of this clinical sign has been increasingly understood. At the same time, clinical diagnostic knowledge has increased, and it has been recognized that this sign may occur sporadically or in association with others within defined clinical syndromes. Thus, in many cases, different therapeutic solutions have become possible. In our work, we have attempted to systematize current knowledge about the origin of this finding, the clinical presentation and current treatment options, to provide an overview that can be used at different levels, from the general practitioner to the specialist neurologist or neurotologist.

Abstract
Background Cervicomedullary glioblastoma is an extremely rare clinical entity and the principles of its management are not well understood. Case Description We report two cases of cervicomedullary glioblastoma in young patients aged 12 and 30 years with contrasting clinical presentation and outcomes. The 12-year-old child had rapid onset bulbar symptoms, with frank infiltration of the medulla due to which the patient succumbed within 4 weeks of surgery. The 30-year-old adult had a relatively slow disease onset and progression and made a good neurological recovery without disease progression at 16 months after surgery. To the best of our knowledge, we also report only the second adult patient in the literature with a dorsally exophytic cervicomedullary glioblastoma. Difficulties in diagnosis and management are discussed with a review of the pertinent literature. Conclusion The overall outcome depends on the rapid progression and severity of preoperative symptoms and the degree of tumor infiltration noted in imaging and during surgery.

Abstract
BACKGROUND To describe the various neuro-ophthalmic presentations, key exam features, and clinical findings associated with 5 common primary and secondary intracranial malignancies. EVIDENCE ACQUISITION Retrospective PubMed search and review of published case reports, case series, observational studies, book chapters, and review articles examining the neuro-ophthalmic features of intracranial malignancies including primary glial neoplasms (e.g., glioblastoma multiforme), primary and secondary lymphoma, intracranial metastases, carcinomatous/lymphomatous meningitis, and intracranial germ cell tumors. The search strategy used to perform the retrospective review included the aforementioned tumor type (e.g., glioblastoma multiforme) and the following terms and Boolean operators: AND ("visual loss" OR "papilledema" OR "diplopia" OR "ophthalmoplegia" or "neuro-ophthalmology" OR "proptosis"). RESULTS The rate of growth and the location of an intracranial tumor are essential factors in determining the neuro-ophthalmic presentation of certain intracranial malignancies. Primary malignant brain glial neoplasms commonly present with visual afferent complaints (e.g., unilateral or bilateral visual acuity or visual field defects, bitemporal or homonymous hemianopsia), pupil abnormalities (relative afferent pupillary defect), and optic atrophy or papilledema. Primary intraocular lymphoma (with or without central nervous system lymphoma) typically presents as a painless bilateral vitritis. Secondary intracranial malignancies have variable afferent and efferent visual pathway presentations. Carcinomatous/lymphomatous meningitis is associated with diplopia (e.g., multiple ocular motor cranial neuropathies with or without vision loss from papilledema or compressive/infiltrative optic neuropathy). Intracranial germ cell tumors can present with a chiasmal syndrome or dorsal midbrain syndrome. CONCLUSION Intracranial malignancies can present with neuro-ophthalmic symptoms or signs depending on topographical localization. Specific neuro-ophthalmic presentations are associated with different malignant intracranial tumors. Clinicians should be aware of the common malignant intracranial tumors and their associated clinical presentations in neuro-ophthalmology.

Abstract
OBJECT The aim of this study is to investigate the impact of surgery for different cervicomedullary lesions on symptomatic pattern expression and postoperative outcome. We focused on specific outcome features of the early and late postoperative assessments. The former relies on surgery-related transient and permanent morbidity and feasibility of radicality in eloquent areas, whereas the latter on long-term course in lower grade tumors and benign tumorlike lesions (cavernomas, etc.). MATERIAL AND METHODS We retrospectively analyzed 28 cases of intramedullary tumors of the cervicomedullary junction surgically treated at our institution between 1990 and 2018. All cases were stratified for gender, histology, macroscopic appearance, location, surgical approach, and presence of a plane of dissection (POD). Mean follow-up was 5.6 years and it was performed via periodic magnetic resonance imaging (MRI) and functional assessments (Karnofsky Performance Scale [KPS] and modified McCormick [MC] grading system). RESULTS In all, 78.5% were low-grade tumors (or benign lesions) and 21.5% were high-grade tumors. Sixty-one percent underwent median suboccipital approach, 18% a posterolateral approach, and 21% a posterior cervical approach. Gross total resection was achieved in 54% of cases, near-total resection (>90%) in 14%, and subtotal resection (50-90%) in 32% of cases. Early postoperative morbidity was 25%, but late functional evaluation in 79% of the patients showed KPS > 70 and MC grade I; only 21% of cases showed KPS < 70 and MC grades II and III at late follow-up. Mean overall survival was 7 years in low-grade tumors or cavernomas and 11.7 months in high-grade tumors. Progression-free survival at the end of follow-up was 71% (evaluated mainly on low-grade tumors). CONCLUSIONS The surgical goal should be to achieve maximal cytoreduction and minimal postoperative neurologic damage. Functional outcome is influenced by the presence of a POD, radicality, histology, preoperative status, and employment of advanced neuroimaging planning and intraoperative monitoring.

Abstract
Pilocytic astrocytoma (PA) is a rare glioma, which generally occurs in children and young adults. In adult patients, the majority of PA tumors are supratentorial. Due to the low morbidity rate of the disease in adults, PA is frequently misdiagnosed and mistreated. In the present study, this rare disease was successfully treated. The study reported the case of a 48-year-old patient with a cervicomedullary occupying lesion, who complained of numbness and pain of the right limbs that persisted for >10 years, with aggravation for 1 month. A magnetic resonance imaging scan showed a sharp cervicomedullary mass extending from the lower medulla to the cervical vertebra C3 level. Intraoperatively, the medulla and upper cervical cord were found to be well-stacked. Immediately after ingression into the spinal cord along the dorsal median sulcus, the tumor mass was detected and had a gray fish-like appearance, moderate blood supply and clear boundary. After intratumoral decompression, total excision was achieved. Postoperative pathological examination confirmed that the tumor was a PA. Following discharge, the patient did not suffer from any symptoms of the lower cranial nerves and was able to walk with limited assistance.

Abstract
OBJECT Cervicomedullary tumors (CMTs) represent a heterogeneous group of intrinsic neoplasms that are typically low grade and generally carry a good prognosis. This single-institution study was undertaken to document the outcomes and current treatment philosophy for these challenging neoplasms. METHODS The charts of all pediatric patients with CMTs who received treatment at St. Jude Children's Research Hospital between January 1988 and May 2013 were retrospectively reviewed. Demographic, surgical, clinical, radiological, pathological, and survival data were collected. Treatment-free survival and overall survival were estimated, and predictors of recurrence were analyzed. RESULTS Thirty-one children (16 boys, 15 girls) with at least 12 months of follow-up data were identified. The median age at diagnosis was 6 years (range 7 months-17 years) and the median follow-up was 4.3 years. Low-grade tumors (Grade I or II) were present in 26 (84%) patients. Thirty patients underwent either a biopsy alone or resection, with the majority of patients undergoing biopsy only (n = 12, 39%) or subtotal resection (n = 14, 45%). Only 4 patients were treated solely with resection; 21 patients received radiotherapy alone or in combination with other treatments. Recurrent tumor developed in 14 children (45%) and 4 died as a result of their malignancy. A high-grade pathological type was the only independent variable that predicted recurrence. The 5- and 10-year treatment-free survival estimates are 64.7% and 45.3%, respectively. The 5- and 10-year overall survival estimate is 86.7%. CONCLUSIONS Children with CMTs typically have low-grade neoplasms and consequently long-term survival, but high risk of recurrence. Therapy should be directed at achieving local tumor control while preserving and even restoring neurological function.
