Successful Management of a Huge Pulmonary Hydatid Cyst in a Young Child: A Case Report.

Hydatid cyst disease is a parasitic disease induced by Echinococcus granulosus, which is still endemic in northern African countries. We report the case of a late-discovered pulmonary hydatid cyst in a four-year-old boy revealed by recent dyspnoea. The chest X-ray showed a complete white-out of the left hemithorax with mediastinal deviation, and the thoracoabdominal CT scan showed a giant pulmonary hydatid cyst encompassing the entire left lung associated with a hepatic cyst. An emergent superior pulmonary lobe resection was performed under deep general anaesthesia and selective intubation to prevent contralateral lung inundation. The evolution was favourable postoperatively.
