[Abstract] Objective: To study the clinical and MRI characteristics of acute transverse myelitis (ATM) after the onset of symptoms.Materials and Methods: The clinical information and MRI features of 56 cases with ATM during Jul.2006~Jul.2012 were analyzed retrospectively, and all patients with a follow-up duration longer than 2 years were identified.Results: (1) Fifty-six cases of ATM patients must have had at least one follow-up visit more than 2 years after the onset of symptoms. 19 cases (33.9 %, 19/56) for multiple sclerosis (MS), 10 cases (17.9%, 10/56) for neuromyelitisoptica (NMO), 3 cases (5.4%, 3/56) for systemic autoimmune disease, 4 cases (7.1%, 4/56) for parainfectious and 20 cases (35.7%, 20/56) foridiopathic were clinically defined. (2) All patients had varying degrees of motor, sensory and autonomic dysfunction below the level of the cord lesions. (3) MRI features: The cervical cord was involved in 18 cases.The thoracic cord was involved in 17cases.The cervical and thoracic spinal cord was all involved in 13 cases.The thoracic and lumbar spinal cord was involved in 8 cases. Thirty-three cases of lesions were associated with swelling, and in other 23 cases the spinal cord showed normal appearance. The average lesion length was 4.7 spinal segment, 29 cases were involved more than two-thirds of the cross-sectional area of the spinal cord, 27 cases occupied less than two-thirds of the cross-sectional area. Contrast-enhanced MR scanning demonstrated that non-enhancement was seen in 15 cases, patchy or strip enhancement were revealed in 41 cases.Conclusions: The combination of clinical characteristics and MRI featurescan improve the diagnosis and differential diagnosis with ATM.
