Pathologie tumorale de la moelle et de ses enveloppes chez l'adulte et l'enfant

Intraductal tumors are rare tumors exhibiting slow progression and varied and nonspecific clinical symptoms. Tumors affecting the cord envelopes mainly develop from nerve sheaths and meninges (meningioma and schwannoma respectively). The most frequent intramedullary tumors are gliomas (astrocytoma in children and ependymoma in adults), but there are many other tumors that are not so rare. The diagnosis is made primarily by magnetic resonance imaging (MRI). Imaging is useful to determine the location of the injury. Tumor location to an anatomical space (epidural and intradural intramedullary) provides the best diagnostic approach. Therapeutic monitoring with MRI allows early diagnosis of recurrence or surveillance of residual tumor tissue.
