Intradural extramedullary spinal ependymomas arising from outside the region of the conus medullaris are rare clinical entities and anaplastic transformation of these lesions is even more exceptional.

Dermoid cysts are benign congenital tumors that develop early in life. These tumors are classified by the presence of all three germ layers. Spinal intradural extramedullary teratoma is a rare disease...
We describe a case of an intradural extramedullary inflammatory myofibroblastic tumor of the cervical spine. A 56-year-old woman presented with progressive neck pain, radiating to the right scapula, w...
Durotomy is a necessary procedure for resection of spinal intradural-extramedullary (IDEM) tumor. The purpose of this study was to investigate the prevalence and clinical implication of pneumocephalus...
Spinal myxopapillary ependymoma (SP-MPE) is a subgroup of ependymomas in which after initial gross tumor resection recurrences occur in more than half of the patients. Anaplastic transformation may al...
Anaplastic transformation of a primary thyroid tumor whose process can be followed is rare. The objective this study is to report a case of anaplastic transformation of locally advanced papillary thyr...
This phase I trial studies the side effects of linear energy transfer (LET) optimized image modulated proton therapy (IMPT) in treating pediatric patients with ependymoma. Radiation therap...
The purpose of the study is to test the effects of intradural, spinal cord stimulation using a device placed in the same manner as a lumbar drain performed during a standard epidural spina...
The goal of this study is to establish the mechanism(s) of progression of primarily spinal syringomyelia (PSS). Our preliminary study of syringomyelia emphasized syringomyelia associated ...
Background: Ependymomas are rare tumors that arise from the ependyma. That is a tissue of the central nervous system. They can develop in the brain or the spine. They are usually treated ...
In this study we are going to compare the effectiveness of robot assisted thoracic surgery (RATS) with video assisted thoracic surgery (VATS) in case of lung cancer. The perioperative cir...
Benign and malignant neoplasms which occur within the substance of the spinal cord (intramedullary neoplasms) or in the space between the dura and spinal cord (intradural extramedullary neoplasms). The majority of intramedullary spinal tumors are primary CNS neoplasms including ASTROCYTOMA; EPENDYMOMA; and LIPOMA. Intramedullary neoplasms are often associated with SYRINGOMYELIA. The most frequent histologic types of intradural-extramedullary tumors are MENINGIOMA and NEUROFIBROMA.
Excessive formation of dense trabecular bone leading to pathological fractures; OSTEITIS; SPLENOMEGALY with infarct; ANEMIA; and extramedullary hemopoiesis (HEMATOPOIESIS, EXTRAMEDULLARY).
Anaplastic lymphoma of the skin which develops as a primary neoplasm expressing the CD30 ANTIGEN. It is characterized by solitary nodules or ulcerated tumors.
Benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes). Astrocytes may give rise to astrocytomas (ASTROCYTOMA) or glioblastoma multiforme (see GLIOBLASTOMA). Oligodendrocytes give rise to oligodendrogliomas (OLIGODENDROGLIOMA) and ependymocytes may undergo transformation to become EPENDYMOMA; CHOROID PLEXUS NEOPLASMS; or colloid cysts of the third ventricle.

Surgery performed on the thoracic organs, most commonly the lungs and the heart.
According to the American Brain Tumor Association, just over 24,000 patients will be diagnosed with a primary malignant brain tumour during 2012 in the US alone. Some 80% of primary malignant brain tumours are gliomas, a broad term which includes all tum...
