ACUTE TRANSVERSE MYELITIS: A CLINICAL REVIEW AND ALGORITHM FOR DIAGNOSTIC INTERVENTION

Introduction. Under the term of acute transverse myelitis (AM), there are included a heterogeneous group of diseases, with the nexus common to produce an inflammatory focal injury of the spinal cord, of acute form. In order to try to group all the etiologies that can provoke this affectation, it is nowadays tried to define several groups of pathologies with a common nexus: those ATM associated to some process, or at least predisposed of the ATM, like are certain infections, immunological systemic and/or multifocal processes, and inclusive tumors, but when we did not get to know this triggering factor, then calling them idiopathic ATM. Aim. To know the different classes from existing ATM, creating an algorithm diagnosis that helps to this classification of ordinate form, simplifying the work to the clinicians that faces a ATM, exposing its differential diagnosis, prognosis and possible treatment. Development. For it we consulted the last guides and works published related to the ATM, mainly from the diagnostic and therapeutic point of view. Conclusions. Our knowledge of the ATM is being constantly modified with the coming of new diagnostic techniques and theories that try to explain their origin, probably immunological. Unfortunately, the treatment, and therefore the prognosis, has not varied in the saute proportion to the knowledge that we are acquiring in the other areas. Without a doubt, it is a way important to walk, but the next future can teach to us more on this disease. [REV NEUROL 2009; 49: 533-40]
