Herniated disc displacing the thecal sac. In all cases, this means that the bulging portion of the disc is making contact to some degree with the thecal membrane and enacting some force against the side wall of the structure. This will produce a noticeable deformity which can be visualized on diagnostic imaging. Thecal sac impingement is often noted on diagnostic imaging reports of people with various back pain and neck pain conditions. The thecal sac is the protective membrane which surrounds the spinal cord and other vital neurological structures. This is a common term you may encounter reading your MRI report. Diffuse cervical bulge means a generalized disc bulge of one of spinal discs of the neck (cervical spine). This bulging material may contact or pinch the thecal sac or nerve roots. Ventral refers to the front, the opposite of posterior. Thecal sac is the outer covering of the spinal cord.
