Other nasopharyngeal cysts include more lateral benign seromucinous retention cysts (Fig. 10), pharyngeal bursae of Luschka (between the longus colli muscle heads) and oncocytic cysts (Warthin's tumor, not reported in children).
Herniated Nucleus Pulposus. Definition. A herniated disc is a fragment of the disc nucleus which is pushed out of the outer disc margin, into the spinal canal through a tear or rupture.. In the herniated disc's new position, it presses on spinal nerves, producing pain down the accompanying leg. This produces a sharp, severe pain down the entire leg and into the foot.
Additionally, patients who have bowel or bladder incontinence as the result of a bulging or herniated disc need to undergo spinal surgery. In the case of bulging and herniated discs, the most common surgical procedure performed is a discectomy. This procedure involves the removal of damaged disc material. If the entire disc is removed, a spinal fusion procedure, which connects vertebrae, may be needed to ensure spinal stability.
