Thoracic kyphosis angle of 42 degrees. >5 degrees anterior vertebral body wedging from T7 to T12 along with endplate irregularity and small Schmorl's nodes from T6-7 to T12-L1. No bone marrow edema.

Case Discussion

Scheuermann disease is a less common cause of scoliosis in adolescents and is secondary to asymmetric endplate changes. Mild syringomyelia has been reported as a not uncommon, incidental finding in patients with Scheuermann disease as well as patients with scoliosis.
