(author) Muchos casos de pacientes con neuromielitis optica se han presentado sin lesiones desmielinizantes en la sustancia blanca cerebral, se ha documentado que esta entidad puede causarlas desde el inicio de la enfermedad o a traves de su evolucion natural. This is the first case that has been reported in the scientific literature of Costa Rica. The degree of disorder is illustrated through a case study, both in the cerebral white matter as spinal cord, in a patient with neuromyelitis optica during a follow-up period of 4 years. Disease in Costa Rica has been little prevalent and is not exactly known what the prevalence and incidence. Diagnostic methods currently as Magnetic Resonance Imaging (MRI) and specific antibodies in plasma (such as antiaquaporin-4) have been diagnosed of neuromyelitis optica cases that were initially confused with multiple sclerosis. Many cases of patients with neuromyelitis optica have submitted without demyelinating lesions in the cerebral white matter, it has documented that this entity can cause from the onset of illness or through its natural evolution.

The contrast medium is injected intravenously (into a vein) as part of an MRI scan, and eliminated from the body through the kidneys. Different brands of gadolinium contrast medium use different chelating molecules. A chelating agent prevents the toxicity of gadolinium while maintaining its contrast properties. The chemical bonds are made between a gadolinium ion and a carrier molecule (a chelating agent). Gadolinium contrast media consist of complex molecules, arrangements of atoms held together by chemical bonds. This allows the radiologist (a specialist doctor trained to examine the images and provide a written report to your doctor or specialist) to more accurately report on how your body is working and whether there is any disease or abnormality present. When injected into the body, gadolinium contrast medium enhances and improves the quality of the MRI images (or pictures). Gadolinium contrast media (sometimes called a MRI contrast media, agents or ‘dyes’) are chemical substances used in magnetic resonance imaging (MRI) scans.
