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.
If no symptoms are present, no particular treatment is necessary. Depending on the severity of symptoms, treatments for a herniated disc include physical therapy, muscle-relaxant medications, pain medications, anti-inflammation medications, local injection of cortisone (epidural injections), and surgical operations.
