- Transverse Myelitis (TM) is the development of grey and white matter inflammation of the spinal cord, which can result in demyelination.
- Hallmark characteristics of this condition include: (1) isolated spinal cord (not brain) dysfunction, and (2) the lack of associated cord compression.
- TM can be acute or subacute, such that it progresses over the course of hours to several days. Nearly half of cases will reach its maximal deficit within 1 to 10 days of onset.
- The diagnosis of TM is primarily based on the history and physical examination findings. MRI of the spinal cord and myelography are often used as diagnostic adjuncts.
- This condition typically presents with paresthesias, back pain, and ascending leg weakness.
- Febrile illnesses often serve as a precursor; one series found this to be the case in 37% of complete TM cases.
- While steroids are sometimes administered over the first several days of illness to decrease inflammation, there is no cure for TM and treatment is largely supportive in nature.
