Recurrence of chest wall hydatid cyst disease involving the thoracic spine in an Australian patient.

Hydatid disease involving the spine is a relatively uncommon occurrence. The cestode Echinococcus granulosus is the primary pathogen associated with hydatid disease and most patients present with signs and symptoms of spinal cord compression depending on the location of the spinal involvement. We present a rare case of recurrent hydatid disease with extensive hemithorax involvement, including the thoracic spine, associated with spinal cord compression.
