The disease usually spreads to the spine by direct extension from pulmonary, abdominal, or pelvic infestation and less often begins primarily in the vertebral body, affecting predominantly the dorsal region of the spine (Bhojraj and Shetty 1999; Garcia-Vicuna et al. 2000; Govender et al. 2000; Hamdan and Al-Kaisy 2000; Schnepper and Johnson 2004; Herrera et al. 2005; Prabhakar et al. 2005; Sapkas et al. 2006; Papanikolaou 2008; Spies et al. 2008). When hydatidosis begins in the spine, it usually begins in the marrow of a vertebral body and may progress around the neural arch, through adjacent ribs, reaching the spinal canal or the intervertebral discs; thus, spinal involvement is believed to occur through direct portovertebral venous shunts (Morshed 1977
