Objective: To investigate the use of ultrasound to diagnose fetal intraspinal cyst in thethird trimester.
Method: A retrospective analysis of two cases of intraspinal cysts was performed. Theimaging characteristics of the two cysts were discussed.
Result: Both cases were of single lance-shaped intraspinal cysts, which were positioned around the terminal conus medullaris along the spinal cord at the side of the dorsal part, mimicking the cord.
Conclusion: Prenatal evaluation of the spinal cord is helpful in detecting intraspinal cysts.
