Bertolotti's syndrome in children: From low-back pain to surgery. A case report.

Bertolotti's syndrome is a little-known and little-discussed pathology. We report the case of a 13-year-old child diagnosed with Bertolotti's syndrome after several years of functional complaints. Conventional radiography was used to diagnose the transverse mega-apophysis of L5, while sectional and functional imaging confirmed a lumbosacral-iliac impingement.
