What indication suggests a newborn has a myelomeningocele?

The indication that suggests a newborn has a myelomeningocele is the presence of a visible defect on the back. Myelomeningocele is a form of spina bifida, which occurs when the spinal column does not close completely during fetal development. This results in a sac-like protrusion on the back that can be seen externally, often containing nerves and spinal tissue. The visible defect is a hallmark sign, and its presence leads to further assessments for potential neurological impairment and associated conditions.

Other symptoms, such as severe jaundice, low birth weight, or excessive crying, do not specifically correlate with myelomeningocele. Severe jaundice is typically related to liver function or hemolytic disease. Low birth weight can stem from a multitude of factors, including maternal health, nutrition, and gestational age, and is not indicative of spinal defects. Excessive crying can indicate discomfort or various other issues but does not point specifically to the anatomical defect associated with myelomeningocele.
