“…[ 3 , 8 , 11 , 12 , 16 , 19 , 20 ] Early diagnosis of SSDH is essential, because the compression can compromise the spinal cord and/or roots of the cauda equina, resulting in permanent neurologic deficit or death. [ 6 , 20 ] SSDH usually presents in between 45 and 60 years of life, with a slight female predominance, predominantly in the thoracic spine, followed by the cervicothoracic and thoracolumbar spine.
