Intra thoracic extra pulmonary hydatidosis: prognosis and outcomes of 8 operated patients.

Hydatid cyst disease is a parasitic disease known from the times of hippocrates, and is still endemic in our country Morocco among others, affecting mainly the liver and lungs, while intra thoracic extra pulmonary location remains a rare entity of the disease. In our department of thoracic surgery, Mohamed VI University Hospital, Oujda, Morocco, we operated 92 patients for thoracic hydatid cyst in the period between January 2016 and December 2021, 8 patients of this group had exclusive extra pulmonary location of the hydatid cyst, epidemiological and clinical data were recorded for the 8 patients (5 men, 3 women). The mean age was 40.3 years, all patients presented mainly with chest pain, dyspnea and cough. The locations of the hydatid cysts were chest wall, pericardium, pleural space and diaphragm. The hydatid cysts were removed via extirpation technique through thoracotomy in all patients. The average duration of hospitalization was 7 days. Postoperative complications consisted of atelectasis in one patient, parietal hematoma in another, and surinfection with pleuro-cutaneous fistula and chronic neurological chest pain in one patient. No deaths were noted in our series.
