Chordomas and Their Consideration in the Radiographic Differential of Extra-Axial Lesions of the Central Nervous
Due to the rare occurrence of chordomas extra-axially, these lesions have not earned a great deal of consideration in the clinical and radiographic differential diagnoses of extra-axial paraspinal lesions. We describe a case of a patient with a surgically resected extra-axial chordoma and review the radiologic characteristics of chordomas as an entity in the spectrum of extra-axial lesions. A 4...
متن کاملExtra-axial chordoma.
A chordoma which occurs as a primary tumour outside the axial skeleton is known as an extra-axial chordoma, parachordoma or chordoma periphericum. It is extremely rare and therefore survival, recurrence and the rates of metastasis are not known. Whilst few recurrences have been described, the extra-axial chordoma has the potential for late recurrence at up to 12 years. Metastases are even less ...
متن کاملExtra-Axial Medulloblastoma in the Cerebellar Hemisphere
Extra-axial medulloblastoma is a rare phenomenon. We report a case in a 5-year-old boy who presented with nausea, vomiting, and gait disturbance. He was treated with total removal of the tumor. This is the first case of an extra-axially located medulloblastoma occurring in the cerebellar hemisphere posteriolateral to the cerebellopontine angle in Korea. Although the extra-axial occurrence of me...
متن کاملSurgical Techniques in Benign Extra-Axial Tumors
Extra-axial tumors are lesions, neoplastic and not, which are external to the brain parenchyma and can originate in the skull, meninges, cranial nerves, and brain appendages such as the pituitary gland. Surgery provides a diagnosis and can be the first step in the treatment. When chosen as a treatment, we should consider the access and the approach to the lesion, the adequate operative techniqu...
متن کاملEpendymoma in supratentorial extra-axial location
E is a common type of pediatric brain tumors (≈10% of all central nervous system tumors in the pediatric age group), it is usually located in the infratentorial compartment and a third of the ependymomas are supratentorial. Of the supratentorial ependymomas, extraventricular ones are rare and usually located in close proximity to the ventricles (some still have connection to ventricle margin). ...
