E Alton Sartor, Patrick Y Wen
Ependymomas are rare primary central nervous system tumors occurring in children and young adults. They can be indolent or locally aggressive depending on location, histology, and extent of resection. Treatment involves maximal surgical resection and usually focal radiation therapy, depending on the presence of residual disease and tumor grade. Chemotherapy has been studied for both adults and children but do not have an established role in adjuvant therapy. In both age groups, treatment with mainly cisplatin based regimens can be considered in the setting of residual disease after surgery or for salvage therapy when surgery or further radiation is not indicated...

Stereotactic radiosurgery (SRS) is the use of a single high dose of radiation, stereotactically directed to an intracranial region of interest, in order to create a lesion or obliterate a preexisting one. This technology has evolved over the years into the use of multiple radiation sources oriented at a variety of angles, thus permitting the creation of various treatment target shapes. This allows for non-open surgical treatment of intracranial pathologies, which significantly decreases the risk of morbidity...

Ependymomas of the posterior fossa in adults are relatively rare, represent less than 1% of adult intracranial gliomas. Most of the cases are WHO grade II. Due to their rarity, there are no randomized studies regarding the best management of these tumors. It seems that surgical resection has a major role in their management. Unlike the scenario in children, these tumors can be cured by gross total resection without adjuvant therapy in the majority of cases. Hence, knowing the different surgical approaches, with their pros and cons, is important in order to offer the patient the best treatment...

BACKGROUNDS: Goals of vestibular schwannoma (VS) microsurgery are: maximal resection, facial nerve (FN) preservation and, in selected cases, hearing preservation (HP). Postoperative HP rates are related to clinical and radiographic factors: size of tumor, preoperative hearing, hypertension, diabetes, and presence or absence of preoperative tinnitus. In this retrospective review we evaluated the influence of preoperative tinnitus on HP after VS surgery in patients with preoperative socially useful hearing (SUH)...

The purpose of this paper is to interoduce and review the characteristic imaging features of ependymal neoplasms through a comprehensive case-based approach. Illustrated cases highlight both common and uncommon manifestations of CNS-ependymomas. The combination of imaging features, location of the tumor, and patient's demographics often allow the suggestion of ependymoma as a lead entity in the differential diagnosis. However, significant overlap exists between the radiologic characteristics of ependymomas and those of other tumors commonly encountered in the same locations, which can pose a challenge for a definitive diagnosis based on imaging alone...

BACKGROUND: Nitric oxide (NO) is synthesized by the conversion of Arginine (Arg) into the NO and Citrulline (Cit). Although the NO is involved into the pathogenesis of several physiological and pathological processes, the role of NO in pituitary adenomas (PA) progres-sion is not determined. Our purpose was to evaluate the relationship between NO and PA as well as the effect of tumor resection on NO metabolites level in serum. METHODS: The study group consisted of 21 patients with PA, 18 patients with macroade-nomas and 3 with microadenomas...

Ependymoma can arise throughout all compartments of the central nervous system with prevalence for intracranial and spinal location in children and adults, respectively. The current histopathology based WHO grading system distinguishes grade I, II 'classic', and III 'anaplastic' ependymoma. However, analysis of multiple cohorts of intracranial ependymoma demonstrate a wide variance in the utility of the grade II versus grade III distinction as a prognostic marker that may additionally be confounded by the anatomic compartment...

BACKGROUND: Tanycytic ependymoma is a rare variant of ependymoma and management guidelines for patients with this disease are not established. METHODS: We performed a systematic search on Pubmed complimented by hand- searching citation lists to identify patients with pathologically confirmed tanycytic ependymoma. Signs and symptoms, radiological and specific pathological findings as well as reported treatment modalities and outcomes were recorded and analyzed. RESULTS: 51 studies involving a total of 77 patients were identified and included in this review...

OBJECTIVE: This study aimed to explore relevant factors of hemorrhagic contusions following decompressive craniotomy (DC) in traumatic brain injury (TBI), and create an artificial neural network (ANN) prediction model of the risk factors of hemorrhagic contusions. METHODS: This study analyzed 425 patients with TBI who underwent DC in the Neurosurgery Department of Shaoxing People's Hospital between 2009 and 2014. Patients were divided into two groups according to the first postoperative CT scans: hemorrhage group and non-hemorrhage group...

BACKGROUND AND OBJECTIVES: Spontaneous spinal extradural hematoma (SSEH) is a rare but disabling disorder. Most of the previous assumptions regarding the factors that contribute to poor neurological recovery from SSEH are based on small case samples or conditions with similar clinical presentations but different physiopathologies. Our goal was to find the most relevant prognostic factors for neurological recovery in patients suffering SSEH treated with surgical evacuation. MATERIAL AND METHODS: From a retrospective database of 29 surgical patients with SSEH, several clinical and radiological variables were recorded...

Craniopharyniomas arise from the sellar region and are particularly challenging because of their close proximity to critical neurovascular structures, including cranial nerves, brainstem, internal carotid arteries, posterior cerebral arteries, hypothalamus, and the pituitary gland. The tumors are benign on histology but can cause serious symptoms by compression of surrounding vital structures. While radical surgery and gross total resection (GTR) remains the first line treatment, choosing the optimal surgical approach is critical for the minimization of complications and post-operative morbidity...

BACKGROUND: Aqueductal stroke volume (ACSV) measured by phase-contrast cine (PCC)-MRI has been proposed with controversy as a tool for the selection of patients with normal pressure hydrocephalus (NPH) as candidates for shunt-surgery. The aim of this study was to assess if PCC-MRI scan measurements of ACSV could select properly these patients. METHODS: We retrospectively reviewed charts and MRI of 38 shunted patients (72,16 ±6,16 years). ACSV measurements were performed 7-30 days before shunt and at the first and sixth months after surgery...
