Tuesday, September 4, 2012

Myelitis is an acute inflammatory process of the spinal cord which causes muscular weakness or paralysis; it could localized or diffused. This medical condition can be caused by bacterial or viral infection. From a pathological anatomy point of view, myelitis myelitis is characterized by loss of myelin and perivascular lymphocytic infiltrates, the presence of plasmocytes and macrophages. If the inflammatory process affects the whole diameter of the spinal cord, in a localized section, it is called transverse myelitis. However, if it spreads along its length, it is known as diffused myelitis. Symptoms depends on the attacked spinal cord areas, paraplegia or quadriplegia, which is paralysis of lower and upper limbs and trunk.
