1/7. Subependymoma of the spinal cord: case report and review of the literature.spinal cord subependymoma is a rare tumour with only 39 reported cases in the literature. The authors report a further case of this neoplasm in a 53 year old man with a progressive paraparesis, paraesthesias of the lower limbs and sphincter disturbance. The tumour was partly removed, without progression 5 years after surgery. After a careful review of the literature, the optimal treatment of this spinal tumour is debated.- - - - - - - - - - ranking = 1keywords = spinal (Clic here for more details about this article) |
2/7. Sudden unexpected death resulting from previously nonsymptomatic subependymoma.A 34-year-old, previously healthy man died suddenly and unexpectedly. The autopsy showed brain and pulmonary edema, numerous small meningeal meningiomas, bilateral and symmetrical juxtaventricular meningiomas, and a well-demarcated gray tan tumor in the medulla oblongata and upper cervical spinal cord. The latter tumor was a subependymoma with features of ependymoma in places. The authors describe and discuss the characteristics of this rare central nervous system tumor, its histogenesis, and its coexistence with other intracranial tumors. The possible mechanisms of death in the present case include compression of vital centers and acute obstruction of the cerebrospinal fluid flow.- - - - - - - - - - ranking = 0.4keywords = spinal (Clic here for more details about this article) |
3/7. Intramedullary subependymoma occupying the right half of the thoracic spinal cord--case report.A 37-year-old female presented with a rare spinal subependymoma manifesting as progressive weakness of her right lower extremity over an 8-month period. She had a 10-year history of back pain and urinary disturbance. magnetic resonance imaging showed diffuse enlargement of the spinal cord from T-2 to T-7 on the T1-weighted images. The enlarged spinal cord was divided into two compartments by a vertical septum-like structure on the T2-weighted images. The tumor occupied the right half of the thoracic spinal cord, and was totally removed through a laminectomy from T-2 to T-7. The histological diagnosis of the resected specimen was subependymoma. Subependymomas are slow-growing tumors usually found in the ventricular system. Spinal subependymomas are difficult to distinguish from other intramedullary spinal tumors based on neuroradiological findings. Subependymomas are surgically curable tumors, so if the tumor is well demarcated and a subependymoma is indicated, an attempt should be made to totally remove the tumor.- - - - - - - - - - ranking = 1.8keywords = spinal (Clic here for more details about this article) |
4/7. Intramedullary subependymoma of the spinal cord: a case report and review of literature.A case of cervical spine intramedullary subependymoma in a 52-year-old female is reported. Also, the relevant literature on the 40 cases reported till date is reviewed. magnetic resonance imaging, even with enhancement, does not show any distinctive features making pre-operative diagnosis often difficult. These tumours are eccentrically located within the spinal cord, thus enabling complete tumour removal in most cases. They are benign with low proliferative potential and hence no post-operative radiotherapy should be administered.- - - - - - - - - - ranking = 1keywords = spinal (Clic here for more details about this article) |
5/7. Massive symptomatic subependymoma of the lateral ventricles: case report and review of the literature.Subependymomas are benign intraventricular tumors with an indolent growth pattern, which are usually asymptomatic, and most commonly occur in the fourth and lateral ventricles. When symptomatic, subependymomas often obstruct critical portions of the cerebrospinal fluid (CSF) pathway, causing hydrocephalus, and range from 3 cm to 5 cm in size. We report a case of an unusually massive subependymoma of the lateral ventricles treated with subtotal resection, ventriculoperitoneal shunt, and post-surgical radiation. The clinical course, radiographic and pathologic characteristics of this massive intraventricular subependymoma are discussed, as well as the differential diagnosis of lateral ventricular masses and a review of the literature concerning subependymomas.- - - - - - - - - - ranking = 0.2keywords = spinal (Clic here for more details about this article) |
6/7. Subependymoma of filum terminale: MR appearance.This report describes a subependymoma of the filum terminale evaluated by MRI. The mass demonstrated hyperintense signal on conventional spin echo T1-weighted, proton density, and T2-weighted imaging and nonenhancement after intravenous gadolinium administration. These characteristics distinguish this lesion from other more common neoplastic and inflammatory lesions arising in the lumbar spinal canal that are typically isointense on T1-weighted spin echo acquisitions, hyperintense on T2-weighted imaging, and enhance variably after intravenous gadolinium administration.- - - - - - - - - - ranking = 0.2keywords = spinal (Clic here for more details about this article) |
7/7. Subependymoma of the cervical cord.Subependymomas are benign lesions of the central nervous system. Their occurrence in the spinal cord is rare. It is important to recognize these lesions because their total surgical excision is feasible and leads to long term symptom remission-a case of a spinal subependymomas localized in the cervical region is discussed and a review of the relevant literature is presented.- - - - - - - - - - ranking = 0.4keywords = spinal (Clic here for more details about this article) |
