Lumbosacral hemangiomas of infancy (hemangioma in the lower back) can be associated with anomalies of the spine. "Tethered cord syndrome" indicates a condition caused by abnormally stretched spinal cord. Over time this condition can lead to neurological damage. Although often there are no symptoms until adulthood, it can become apparent during childhood. Common symptoms are: lower back pain, pain and weakness of the legs, walking problems, and bladder and bowel loss of control. "Occult spinal dysraphism" is the term used when the defect of the spine is hidden under normal skin. We noticed that infants with hemangioma in the lower back area are more inclined to present a hidden spine defect.
