title: Spinal involvement in alveolar echinococcosis: assessment of two cases.
abstract: Two cases of spinal involvement in alveolar echinococcosis are reported. Conventional radiographs showed bone lysis and spondylitis; computed tomographic scans showed detail of local spread to the ribs, other vertebrae, and soft tissues. Differential diagnosis, which includes other infections and hydatidosis, is difficult, and the diagnosis may be suggested by evidence of a primary hepatic focus, geographic propensity to the infection, and laboratory findings.
