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.
Most adults with scoliosis donât require surgery, although it may be considered if: 1  the amount of spinal curvature is greater than 50 degrees. 2  the curvature progresses 5 degrees or more within one year and the curve is greater than 40 to 45 degrees.3  pain is persistent and severe.or example, in a 2010 study of almost 1,300 adults with back pain who had a magnetic resonance imaging (MRI) scan, Johns Hopkins researchers found that 13 percent of people age 46 to 60 and 39% of those over age 60 had lumbar (lower back) scoliosis.
