{{short description|Acute transverse myelitis (ATM) is an inflammatory demyelinating disorder of the spinal cord that can be either idiopathic (IATM; see this term) or secondary to a known cause (SATM; see this term)}}{{Infobox medical condition (new) | name = Transverse myelitis | image = Transverse_myelitis_MRI.jpg | caption = An MRI scan showing a transverse myelitis lesion (the lesion is the lighter, oval shape at center-right), this MRI scan was taken 3 months after patient recovered | field = Neurology | symptoms = | complications = | onset = | duration = | types = | causes = Uncertain[1] | risks = | diagnosis = Neurological exam[1] | differential = | prevention = | treatment = Corticosteroids[1] | medication = | prognosis = | frequency = | deaths = }}Transverse myelitis (TM) is a rare neurological condition in which the spinal cord is inflamed. Transverse implies that the inflammation extends across the entire width of the spinal cord.[4] Partial transverse myelitis and partial myelitis are terms used to define inflammation of the spinal cord that affects part of the width of the spinal cord.[4] TM is characterized by weakness and numbness of the limbs, deficits in sensation and motor skills, dysfunctional urethral and anal sphincter activities, and dysfunction of the autonomic nervous system that can lead to episodes of high blood pressure. Signs and symptoms are variable and reflect the level of the affected spinal cord. The underlying cause of transverse myelitis is unknown. The spinal cord inflammation seen in TM has been associated with various infections, immune system disorders, or damage to nerve fibers, by loss of myelin sheaths.[4] Decreased electrical conductivity in the nervous system can result.{{citation needed|date=July 2018}} Signs and symptomsSymptoms include weakness and numbness of the limbs, deficits in sensation and motor skills, dysfunctional urethral and anal sphincter activities, and dysfunction of the autonomic nervous system that can lead to episodes of high blood pressure.[4] Symptoms typically develop over the course of hours to a few weeks.[2][3] Sensory symptoms of transverse myelitis may include a sensation of pins and needles traveling up from the feet.[2] The degree and type of sensory loss will depend upon the extent of the involvement of the various sensory tracts, but there is often a "sensory level" at the spinal ganglion of the segmental spinal nerve, below which sensation to pain or light touch is impaired. Motor weakness occurs due to involvement of the pyramidal tracts and mainly affects the muscles that flex the legs and extend the arms.[2] Disturbances in sensory nerves and motor nerves and dysfunction of the autonomic nervous system at the level of the lesion or below, are noted. Therefore, the signs and symptoms depend on the area of spine involved.[12] Back pain can occur at the level of any inflamed segment of the spinal cord.[2] If the upper cervical segment of the spinal cord is involved, all four limbs may be affected and there is risk of respiratory failure – the phrenic nerve which is formed by the cervical spinal nerves C3, C4, and C5 innervates the main muscle of respiration, the diaphragm.{{citation needed|date=July 2018}} Lesions of the lower cervical region (C5–T1) will cause a combination of upper and lower motor neuron signs in the upper limbs, and exclusively upper motor neuron signs in the lower limbs. Cervical lesions account for about 20% of cases.[12] A lesion of the thoracic segment (T1–12) will produce upper motor neuron signs in the lower limbs, presenting as a spastic diplegia. This is the most common location of the lesion, and therefore most individuals will have weakness of the lower limbs.[{{cite book | vauthors = Alexander MA, Matthews DJ, Murphy KP |title=Pediatric
