Flattening of the spinal cord is essentially compression of the thecal sac which surrounds the cord and when severe will cause. Imaging findings like thecal sac flattening and foraminal narrowing indicate nerve involvement, which may improve with conservative care. Thecal sac effacement describes the compression or flattening of a protective structure within the spine. Thecal sac indentation occurs when external factors, such as a herniated disc or spinal stenosis, exert pressure on the sac, causing it to.
