Then they must check each tiny sensory nerve rootlet to decide whether or not to cut it.
It is unclear why cutting sensory nerve rootlets decreases spasticity, but doctors believe that decreasing the number of messages being sent from the muscles to the brain causes the muscle tone control system to work more effectively.
CT myelography clearly revealed that the mass was intradural and was compressing the cauda equina nerve rootlets (Figure 2).
Caption: Figure 4: (a) On dorsal dural incision, a mass is observed between the nerve rootlets. (b) A dissector and sucker were used to carefully peel the adherent nerve rootlets away from the disk fragment.
The goal of imaging the BP is to visualize the entire course of the neural network from its preganglionic segments (eg, nerve rootlets and intraforaminal nerve segments) and the postganglionic segments from the dorsal root ganglion (DRG) to the terminal branches.
The preganglionic segments include the cervical spinal cord root entry zone of the ventral and dorsal nerve rootlets, the intrathecal course of these rootlets, and their intraforaminal course up until the DRG.
High-resolution 3D T2- and CT myelography images can show anatomical continuity or lack thereof of intradural nerve rootlets. (5, 6, 9, 12) The course of the rootlets should be followed from the root entry zone to the DRG in the neural foramen.
These included patient 1 with a multiloculated cyst, possibly of arachnoidal origin (Figure 1, A), in which innumerable S100-positive nerve rootlets
were entrapped in cyst wall.
