Atypical Giant Hydatid Cyst at the Thoracic Wall Causing Bone and Soft Tissue Destruction: Report of a Case

Abstract

Hydatid cyst is a zoonotic disease that is common in the Mediterranean region. Thoracic wall, rib or extrapulmonary intrathoracic localization of the cysts is very rare. Giant extrapulmonary intrathoracic hydatid cysts can lead to both diagnostic and treatment difficulties and can be confused with tumor. We present a case of a hydatid cyst with thoracic wall involvement mimicking tumor. We confirmed diagnosis only by surgical exploration and histopathological examination because radiology is not conclusive. Surgical treatment involved the total extirpation of cyst together wide debridement and resection of affected tissue. Primary thoracic wall closures were performed. In thoracic wall localization of cyst, post-operative course of albendazole for 6 weeks associated with surgery can help in sterilizing the cyst and reduce the recurrence rate. In this article, we presented a thoracic wall hydatidosis which is very uncommon asymptomatic presentation of hydatid cyst disease with its surgical management.
