Background:
Hydatid cystic disease is still a significant clinical problem in endemic countries, particularly in Morocco. Mediastinal localization is very rare. We report our surgical experience with this particular lesion.
Patients And Methods:
In a retrospective review of the last ten years (1990-1999), we had seven cases of mediastinal localization out of total of 2332 (0.3%) intrathoracic hydatid cysts treated in our service. Imaging investigation consisted of chest x-ray and computed tomography. All diagnoses were confirmed peroperatively macroscopically and for some lesions, histologically.
Results:
Complete resection of the cyst was performed in six cases. In one case, a small part of the wall intimately adherent to the superior vena cava was left in place. There were no complications, mortality or recurrence.
Conclusion:
Hydatid cysts can be found in many different sites in the body. Whenever possible, surgical management is the best treatment but extensive resection should be avoided. Medical treatment as an adjunct to surgery is indicated when there is a risk of dissemination.
