Patient's question:
When born, there was a 1x1.5 cm skin abnormality and indentation about 3 cm above the buttocks. An MRI was performed, and the results showed that the spinal cord tip is now at the upper edge of L4. The examination conclusion is: spinal cord tethering, vertebral crypt, and abnormal signals at the northern level of L5-S1 vertebra.Doctor's answer:
Above the anus, near the coccyx, there can be a small pit, which is due to the complexity of human anatomy. It's not necessary for everyone to have the same appearance. I often see this in clinical practice. You don't need to worry. Hidden spinal dysraphism is not as scary as you imagine. When I treat adults over 45 with lower back pain, I often take an X-ray first, and sometimes this condition is discovered, while the patient was previously unaware and showed no abnormal symptoms. X-rays should absolutely not be used to examine such young children.
