title: Magnetic resonance imaging for spinal cord tumors. A report of twenty cases.
abstract: This paper discusses spinal cord tumors including imaging characteristics with emphasis on magnetic resonance imaging and advances in treatment. This is a retrospective study of 20 cases patients with neoplasms arising from the spinal cord. All of our cases were explored by magnetic resonance imaging (1.5T) using T1-weighted imaging (Spin Echo), T2-weighted imaging (Spin Echo) and T1-weighted imaging with Gadolinium administration. Pain is the earliest symptom, characteristically occurring at night when the patient is supine. Ependymoma were observed in 11 cases. Astrocytoma was noted in five cases. Other uncommon tumors were identified in four cases: oligodendroglioma (n=1), epidermoid cyst (n=1), hemangioblastoma and metastasis (n=1). In MRI most tumors are isointense or slightly hypointense compared to the normal cord signal with homogenous or irregular enhancement. We describe the characteristic magnetic resonance findings and differential diagnosis of spinal cord tumors. Spinal cord lesions comprise approximately 2-4% of all central nervous system neoplasms. Magnetic resonance imaging plays a central role in the imaging of spinal cord neoplasms.
