INTRODUCTION: Posterior third ventricle ependymomas with intraaqueductal extension are relatively infrequent lesions. Its surgical management represents a formidable technical challenge and includes a wide variety of approaches. Minimally invasive surgery including the endoscopic management can play a crucial role to obtain an optimal clinical outcome. PATIENTS AND METHODS: We report the clinical outcome of an 11-year-old female patient with a 6-year history of recurrent episodes of headache and vomiting...

Intramedullary spinal cord tumors (IMSCTs) are relatively infrequent lesions with ependymomas and astrocytomas representing the most common types. Microsurgical resection is established as the treatment of choice for these challenging lesions. We reviewed the surgical outcome of 29 cases operated for IMSCTs by the same surgeon between 2009 and 2015. The median follow-up period was 31 months, and all patients were followed up at least for 1 year. Among these 29 cases, 5 patients were previously operated for partial resection elsewhere...

This 48-year-old-man who had undergone right thyroid lobectomy for undifferentiated thyroid carcinoma nine years earlier developed generalized seizures. His cerebrospinal fluid was xanthochromic with elevation of total protein. Computed tomography (CT) showed mixed-density bilateral ventricular masses. Magnetic resonance imaging (MRI) revealed multiple nodules in both lateral ventricles; they were heterogeneously enhanced by gadolinium. Diffuse hyperintensity in the right medial temporal lobe and bilateral subependymal area was noted on fluid-attenuated inversion recovery images...

Loss of function mutations in the neurofibromatosis Type 2 (NF2) gene, coding for a tumour suppressor, Merlin, cause multiple tumours of the nervous system such as schwannomas, meningiomas and ependymomas. These tumours may occur sporadically or as part of the hereditary condition neurofibromatosis Type 2 (NF2). Current treatment is confined to (radio) surgery and no targeted drug therapies exist. NF2 mutations and/or Merlin inactivation are also seen in other cancers including some mesothelioma, breast cancer, colorectal carcinoma, melanoma and glioblastoma...

BACKGROUND: Pilocytic astrocytoma (PA) is the most prevalent central nervous system (CNS) tumor in pediatric population and accounts for an approximate of 5-6% of all gliomas. This neoplasm can occur at all levels of the neuraxis, with majority (67%) arising in the cerebellum and optic pathway. PAs are World Health Organization Grade I tumors and are the most benign of all astrocytomas characterized by an excellent prognosis. Other differentials include subependymal giant cell astrocytoma (SEGA), ependymoma, meningioma, and low-grade gliomas such as pilocytic or diffuse astrocytoma; calcification is more commonly regarded as a feature of benign or slow-growing tumors...

Narrative Medicine sessions can encourage patients to rediscover personal identity and meaning by telling or writing their stories. We explored this process to improve care and quality of life for brain cancer patients in an academic neuro-oncology program. Brain cancer and its treatments may threaten a patient's quality of life and sense of self in many ways, including impaired cognitive skills, loss of memory, reduced coordination, and limited capacity for self-expression. The impact of symptoms and side effects on quality of life must be evaluated in terms of each patient's identity and may be understood in terms of each patient's story...

Surgical resection of intramedullary spinal cord ependymoma still remains the standard of care but is challenging and occasionally associated with poor outcome. The aim of this study is therefore to provide additional information regarding the natural history of conservatively treated symptomatic intramedullary spinal cord ependymoma. Retrospective, single center review of all patients with intramedullary spinal cord ependymoma treated conservatively (wait and see) between 1980 and 2016. The neurological outcomes at first presentation, as well as in long-term follow-up, were assessed using the modified McCormick Disability Scale and modified Rankin Scale...

Spinal intradural extramedullary inflammatory pseudotumor (IPT) is an extremely rare entity. Spontaneous shrinking of a spinal IPT has never been reported. A case of an IPT of the cauda equina that regressed spontaneously is presented. A 78-year-old woman presented with hypoesthesia of both lower legs in the L4 nerve root distribution and motor weakness of the right leg. Preoperative CT myelography and MRI showed two tumor-like lesions located at T12-L1 and L2-3. The lesion at the T12-L1 level appeared to encase several nerve roots...

Tanycytic ependymoma is a rare subtybe of ependymoma with a predilection for the spinal cord and intracranial tanycytic ependymoma is thus extremely rare. Most studies on intracranial tanycytic ependymomas included only one or two cases. Here we report nine patients with pathologically confirmed intracranial tanycytic ependymomas. The clinical characteristics, including radiological and histological examination, operative records, and prognoses were reviewed. The case series included six male and three female patients with an average age of 19...

OBJECTIVE: Spinal cord tanycytic ependymomas (TEs) are rarely reported because of extremely low incidence. Understanding of this disease is therefore poor. The aim of this study was to analyze the incidence and clinical, radiological, pathological, and prognostic features of spinal cord TEs. METHODS: Approximately 4,000 spinal cord tumors were surgically resected in Beijing Tiantan Hospital between April 2009 and May 2016. We identified all cases of pathologically proved TEs among these patients...

Ependymoma is a locally aggressive tumor with metastatic potential that arises in diverse locations throughout the brain and spine in children. Tumor and treatment may result in significant morbidity. Cure remains elusive for many patients owing to diverse biology and resistance to conventional therapy. The implementation of systematic postoperative irradiation in clinical trials during the past 20 years has increased the proportion of patients achieving durable disease control with excellent results, as measured by objective functional outcome measures...

Ependymal tumours in adults are rare, accounting for less than 4% of primary tumours of the central nervous system, and exceptionally metastasise outside the nervous system. In this study, we present a case of anaplastic ependymoma, which developed metastases outside the nervous system less than a year after its clinical onset. A healthy 65-year-old woman suddenly presented with drowsiness of unknown origin, accompanied by ingravescent fatigue, inability to maintain the upright posture, headache, nausea and vomiting...
