Background
Hydatid cyst caused by E. granulosus can develop in any organ but undoubtedly, hepatic and pulmonary localizations are most frequent. The anterior thoracic wall is avery rare site of infestation. constituting only 0.1%of all infections. This rarity can cause dilemma and if surgery is carried out unaware of the diagnosis, spilling of the cyst will result in dissemination of the disease.The aim of the present study is to report a rare case of primary hydatid cyst located at anterior thoracic wall .
Material and Methods
A 44-year-old man presented with a painless lump at the anterior thoracic wall for past two years. Physical examination revealed a 8x5 cm, semimobile, well-defined mass. Blood tests (complete blood count and blood chemistry) and the patient's past medical history were unremarkable. Ultrasonography and MRI revealed a cystic mass with regular borders, 10 cm in diameter.
Result
The cystic mass was excised without spilling under general anaesthesia. Macroscopic and microscopic examination of the specimen confirmed a hydatid cyst. Postoperative course of the patient was uneventful, and computed tomography scans of the thorax and abdomen showed no evidence of hepatic or pulmonary involvement.
Conclusion
Although hydatid cysts at the anterior thoracic wall are rare, they should be considered in the differential diagnosis of cystic lesions, especially in endemic regions. If a definite diagnosis can not be made before the operation, great care must be taken to avoid spilling of the cystic contents. Abdominal ultrasonography and a plain chest radiograph are mandatory to exclude liver and lung involvement.
