55+8-year-old female had a very unusual and severe truncal decompensation brought on by a cyst around her spinal cord in the cervical region. This produced a truncal deformity where she leaned severely to the right and forward thus could not stand upright to any extent. She underwent a posterior reconstruction and realignment from the upper thoracic region all the way to the sacrum and ilium followed by a second stage anterior fusion/cage procedure of the lower three lumbar levels. She obtained nearly perfect posture following surgery and now is able to maintain an upright trunk without any difficulty.
