Abstract: Introduction Spinal extradural arachnoid cysts (SEACs) are rare expansive lesions that account for~1% of all spinal tumors. They develop as the result of arachnoid membrane herniation through a small dural defect and are mostly reported to be located at lower thoracic region and thoracolumbar junction. Case presentation We report a rare case of SEAC located in the cervicothoracic junction causing neurologic compression. Discussion Only 3% of all SEACs are observed in the cervical spine. They are the most commo… Show more

“…likely the result of extension of arachnoid into the epidural compartment). [ 17 ] EDAC fill and enlarge based upon a one-way, ball-valve mechanism of the fistulous communication between the subarachnoid and epidural spaces; in short, CSF flows into the cyst, but becomes entrapped, and cannot exit.…”

“…EDAC comprise 1% of all spinal tumors, and are typically found at the thoracic/thoraco-lumbar regions, but only rarely (3%) occur in the cervical spine [ Table 1 ]. [ 17 ] EDAC are typically found dorsal to the cervical/thoracic cord or cauda equina, and may be post-traumatic in origin [ Table 1 ]. [ 5 , 11 , 17 ] In 2013, Choi et al .…”
