Spinal Cord Astrocytoma-MRI

Intramedullary Cord Tumours

Ependymoma-The most common intrinsic spinal cord tumor has a male predilection and a fourth-decade prevalence. They occur anywhere in the cord and are commonly in the conus medullaris, where an exophytic component may be present. They rarely change growth characteristics and metastasize. Lesions are characteristically hypovascular, well circumscribed, and noninfiltrative of the surrounding cord. Symptoms are due to compression of the surrounding cord rather than infiltration. Complete resection often results in prolonged survival.

Astrocytoma These lesions are more common in children than in adults. Sometimes they are associated with microcysts or syrinxes. The pilocytic varieties are well differentiated and tend to be indolent, with a definable surgical plane. Fortunately, anaplastic astrocytoma or glioblastoma are rare. Surgical therapy does not improve the dismal course, with death usually occurring within 2 years
