Intramedullary tumors are a subgroup of spinal tumors and are associated with high morbidity and mortality. The estimated incidence of spinal tumors in general is 0.74 to 1.6 per 100 000 persons per year, with intramedullary tumors making up 10% to 30% of the total. The diagnosis is often delayed because of the insidious onset of symptoms, which are often nonspecific at first. ⋯ Patients with intramedullary tumors should be cared for, as much as possible, in the setting of prospective, uniform studies of their spontaneous course and the outcomes after treatment. This will yield better evidence on the treatment of these tumors in the future.
