- Acute noncompressive myelopathies
Definitions
- Acute transverse myelopathy (ATM) is broad generic term encompassing heterogeneous group of disorders causing cord dysfunction
- Etiologies include inflammatory causes (ATM) + vascular disease + radiation + paraneoplastic + idiopathic (unknown)
- ATM more specific term for cord dysfunction that is inflammatory in etiology
- Inflammation defined by CSF findings and MR enhancement
- Acute transverse myelopathy (ATM) is broad generic term encompassing heterogeneous group of disorders causing cord dysfunction
