title: Sacral hydatid cysts with intrapelvic extension presenting as herniated intervertebral disc.
abstract: Hydatid disease of bone is a rare condition. Although the bones most often involved are the vertebrae, sacral vertebral involvement is extremely rare. Prognosis is poor despite extensive medical and surgical treatment. In this paper we present two unusual cases of hydatid disease located in the sacral vertebrae with extension into the pelvic cavity causing radicular symptoms.
