A congenital nevus is a proliferation of benign melanocytes that is either present at birth or develops shortly afterwards. Congenital nevi are usually classified by size: small (less than 1.5 cm in diameter), medium (larger than 1.5 cm and up to 20 cm) or giant (measuring 20 cm in diameter or larger).
Scoliosis is a common condition related to syringomyelia in children; in fact, some studies have shown that more than 50% of children with a syrinx have abnormal spinal curvature.coliosis can be caused by congenital conditions, neurological conditions (like SM), or can be of unknown origins. 80% of scoliosis cases have an unknown cause and are labeled idiopathic. Treatment options include observation, bracing, and surgery.
There are a few different risk factors for developing scoliosis including: 1  Age: Usually, signs and symptoms for scoliosis occur when your child is growing or during a growth spurt. 2  Sex: As mentioned previously, although boys and girls can develop scoliosis, girls have a higher risk of having the curve worsen.
