Multiple pleural hydatid cysts associated with destruction of the vertebral column through an intervertebral foramen Is an uncommon clinical entity. We present a 22-year-old man who underwent left thoracotomy for the removal of multiple pleural hydatid cysts associated with destruction of the vertebral column. In his history, he was operated for the removal of a left lung hydatid cyst at the age of eight. He had back pain and his physical examination was normal. A thoracal computed tomography (CT) scan revealed cystic lesion which eroded the costotransverse joint of the fourth thoracal vertebra and caused destruction of the vertebral column.
