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.
Syringomyelia is a rare disorder in which a cyst forms within your spinal cord. As the cyst, which is called a syrinx, expands and lengthens over time, it compresses and damages part of your spinal cord from its center outward.Damage to the spinal cord caused by a syrinx can cause symptoms like progressive pain, stiffness, and weakness in the back, shoulders, arms, and legs.Individuals with the disorder might lose the ability to feel cold and pain normally.ymptoms of the disorder are caused by the pressure the syrinx puts on the spinal cord and the damage that follows. The symptoms may include: 1  progressive weakness and pain in back, shoulders, arms, or legs. 2  inability to feel hot or cold normally.
