To characterize the topography and vascular territories in lesions produced by acute spinal cord strokes.
Spinal cord strokes are underreported and often misdiagnosed as “transverse myelitis”.
Sixty-one patients with spinal cord strokes seen between 2015 and May 2021 were analyzed at a specialized referral center. Lesion distribution on T2 weighted sagittal and axial MRI was identified and compared to previously established predictive vascular territories after a review of MRIs by 2 independent neurologists.
Out of 61 subjects with spinal cord strokes, most were female (n=36, 59%) and the median age at onset was 54 [IQR 38-61] years. On MRI, most lesions were monofocal (n=44, 72%), and presented as short length (51%). Stroke-lesions affected the cervical cord in 27 (44%), the thoracic cord in 43 (70%) and the lumbar cord-conus in 25 (41%) subjects. Most of the lesions involved the anterior (85%) and central (82%) compartments of the cord while 58% involved the posterior region. In the cervical cord, strokes involved the vertebral artery (VA) anterior spinal artery (ASA) territory in 26 (43%) subjects and the VA-posterior spinal artery (PSA) territory in 8 (13%). Only one subject had exclusive VA-PSA involvement. The ASA territory was compromised in the cervicothoracic region in 27 (45%) patients and in the thoracolumbar region (artery of Adamkiewicz’s territory) in 30 (50%) patients. Fifteen (25%) cases involved the posterior conus watershed territory. Six patients (10%) exhibited associated vertebral bone infarction. Classic imaging findings of spinal cord ischemia such as owl’s eyes and H sign were observed in 19 (32%) and 13 (22%) patients, respectively.
Spinal cord strokes presented frequently in the thoracic cord segments and watershed areas. Bone infarctions, “owl's eyes” and H sign can support the diagnosis of vascular ischemic myelopathies but are not a common finding.
