A case of Bertolleti's syndrome

Lumbosacral Transitional Vertebrae (LSTV) (Bertolleti’s syndrome) is known as a congenital spinal anomaly in which abnormal transverse process of last lumbar vertebra fuses partially or completely with first sacral segment. Here we reported a case of 16 years old girl who referred with pain in the left supragluteal region. Standard AP radiograph showed an abnormal fusion between the transverse process of the left lumbar vertebra and sacral bone. The Bertolleti’s syndrome was diagnosed.
