Transverse myelitis (TM)is a neuroimmunologic disorder that presents with a constellation of symptoms involving varying degrees of sensory, motor, and autonomic dysfunction. These symptoms may develop suddenly over a few hours or gradually over a period of several weeks, complicating evaluation and diagnosis. While TM is not a common disease (approx 1400 new cases per year in the US), it is both debilitating and treatable, thus requiring an accurate and efficient diagnosis. TM shows no race or gender preference, or familial predisposition. It can affect both children and adults of all ages; however, peak ages are between 10 to 19 years and 30 to 39 years.
