Tailgut cyst: MRI evaluation

OBJECTIVE. The purpose of our study was to evaluate the MRI features of tailgut cysts in five patients. CONCLUSION. Our results suggest that MRI may be useful in the diagnosis of tailgut cyst. A multilocular cystic mass in the presacral space is a characteristic MRI finding of tailgut cyst, which may also be revealed as a cystic mass consisting of a large cyst accompanied by a small peripheral cyst. However, further studies are necessary to establish the usefulness of MRI for evaluating tailgut cysts.
