Background: Acute transverse myelitis(ATM) is a group of disorders characterized by focal inflammation of the spinal cord and resultant neural injury. It can be diagnosed by Transverse Myelitis Consortium WorkingGroup(TMCWG) criteria. But there are some cases which were not satisfied with idiopathic ATM criteria, both clinically and radiologically, especially in acute stage. So we analyzed 27 cases retrospectively, which were diagnosed as idiopathic ATM.

Methods: All the records of the patients at Gil Medical Center with a diagnosis of idiopathic ATM from 2001 to 2005 were reviewed. And clinical manifestations including neurological examination, radiologic features and cerebrospinal fluid (CSF) findings were analyzed.

Results: Among the patients(20 men and 7 women; mean age, 45.3 years), 11 cases could not be diagnosed as idiopathic ATM according to the TMCWG criteria ; 6 cases did not have well marginated upper sensory level and 5 cases were not satisfied with spinal cord inflammation.

Conclusions: Although most cases of suspected idiopathic ATM were suitable for TMCWG criteria, some cases were not satisfied with this diagnostic criteria, especially in acute stage. Subsequent study might be needed to evaluate the reliability and clinical application of the criteria.
Key words: Acute Transverse Myelitis, Diagnosis, Analysis, Retrospective.
