متن کاملIntramedullary spinal cord meningioma in a Boxer: a case report
Meningiomas are the most common primary tumours of the canine central nervous system. The incidence of these tumours increases with age and they are more frequently encountered in dogs older than seven years. Meningiomas are solitary, well-defined neoplasias that more commonly grow via compression and less commonly by infiltrating the nervous tissue. Meningiomas exhibit 82% intracranial, 15% in...
متن کاملCT in Myelography of Intraspinal Masses
Computed tomographic (CT) myelography subsequent to nonionic water-soluble contrast medium myelography has provided additional diagnostic information for evaluating intraspinal mass lesions. In 20 patients thus studied, there were eight intramedullary tumors, eight intradural extramedullary masses, and four extradural neoplasms. In intramedullary tumors CT enabled more precise delineation of th...
متن کاملExtra and Intramedullary Anaplastic Ependymoma in Thoracic Spinal Cord
Spinal ependymoma occupies 40-60% of primary spinal cord tumors and has a feature of intramedullary tumor. The tumor most commonly arises from the central canal of the spinal cord, the conus medullaris or the filum terminale and its pathological features are usually benign. Unlike above characteristics, intra and extramedullary ependymomas are reported very rarely and have wide variety of histo...
