Figure 5 Intraoperative pictures showing white chalky material deposited in the epidural space of the posterior and lateral spinal canal (A). This material was partially encapsulated by fibrous tissue and grossly infiltrated the bone and soft tissue in several areas, which was removed completely with a curette (B and C).
