Ependymoma is the third most common pediatric primary brain tumor. Ependymomas are categorized according to their locations and genetic abnormalities, and these two parameters are important prognostic factors for patient outcome. For supratentorial (ST) ependymomas, RELA fusion-positive ependymomas show a more aggressive behavior than YAP1 fusion-positive ependymomas. Extracranial metastases of...

This report presents a case of widespread intramedullary giant cell ependymoma arising from the central canal of the C4 segment of the spinal cord in a 28-year-old man admitted to hospital with tetraplegia and signs of increased intracranial pressure, eight months after surgical spinal cervical decompression without tetraplegia improvement. Magnetic resonance imaging and autopsy revealed a tumo...

diagnosis, degree of surgical resection or prior treatment and subsequent development of extraneural metastases was found [4]. The exact route of extraneural metastases is not known, but in the vast majority metastases occurred in the wake of craniotomy, suggesting iatrogenic vascular seeding [3]. Typically, extraneural metastases of ependymoma occur in the lungs, pleura, and lymph nodes while ...

Ependymoma are rare glial neoplasm, it rarely metastasize outside the central nervous system. We present a case of anaplastic ependymoma with extraneural metastases with review of literature. A ten-year-old male child presented with anaplastic ependymoma of choroid plexus and treated with craniospinal radiotherapy in 1998. He had intracranial recurrence in 2004, confirmed by biopsy. He was give...

OBJECTIVE Ovarian anaplastic ependymoma is a rare gynecologic malignancy that poses diagnostic and treatment challenges. Treatment of sub-optimally debulked disease usually portends poor prognosis. Molecular testing of tumor specimen can identify more specific targets for additional therapy such as estrogen and progesterone receptors (ER/PR). CASE A 29-year-old woman presented with incidental...

Superficial siderosis of the central nervous system is a very uncommon disorder. We report a rare case of spinal ependymoma in a 58-year-old man whose main complaints at presentation were recent lumbago and headache, and he was evaluated to confirm suspected spinal subarachnoid hemorrhage (SAH). After cerebrospinal fluid analysis and imaging studies the patient was diagnosed with SAH and superf...

Intradural extramedullary spinal ependymomas are extremely rare. Herein, we describe a lesion-type spinal ependymoma that followed a malignant course, and discuss its clinical presentation, etiopathogenesis, and treatment. We present a patient who was diagnosed with an intradural extramedullary spinal tumor at T4-T6. The patient underwent gross total resection of the tumor without damage to the...

We report a 10-year-old boy with supratentorial cortical ependymoma that rapidly grew in the course of 3 years. He suffered generalized seizures when he was 5 years old; MRI showed a small cortical lesion in the right postcentral gyrus. MRI performed 2 years later revealed no changes. For the next 3 years he was free of seizures. However, at the age of 10 he again suffered generalized seizures ...

OBJECTIVE Ependymomas are rare intracranial neuroepithelial tumors and the most common location is intramedullary. The aim was to analyze the characteristics of these tumors to determine the patients' overall survival and the likelihood of recurrence. METHOD Data of clinical presentation, tumor location, duration of symptoms, degree of resection and complementary treatment of 34 patients with...
