This syndrome can be caused by a heterogeneous group of disorders, including acute transverse myelitis (ATM). Definitions of ATM have varied significantly in the literature.1,2 To address this nonuniformity, the criteria proposed by the Transverse Myelitis Consortium Working Group3 (Table 18–1) should be used to establish the diagnosis and guide the differential diagnosis and workup. The diagnosis of ATM can be further refined by determining whether there is partial or complete involvement of the spinal cord in the axial plane. Complete ATM is characterized by moderate to severe symmetric symptoms, while partial ATM is marked by milder, asymmetric symptoms.4
