Carpal tunnel syndrome is rare in children. When it does occur in children, the most common causes reported are mucopolysaccharidosis and mucolipidosis. The median artery is a transitory vessel that develops from the axillary artery in early embryonic life and does not normally survive until postfetal life. In a small percentage of individuals, however, it persists into adulthood and is frequently accompanied by a bifid median nerve. A persistent median artery can be a cause of carpal tunnel syndrome in adults, but it is extremely rare in children and adolescents. This paper reports a case of a carpal tunnel syndrome caused by a persistent median artery and bifid median nerve in a 13-year-old girl.
