Hydatid disease of the first rib causing thoracic outlet syndrome.

OBJECTIVE

To present a case of hydatid disease of the first rib as a rare cause of thoracic outlet syndrome.

CLINICAL PRESENTATION: A 57-year-old female patient who had suffered from pain on the left shoulder radiating to the arm and numbness and weakness on the left arm for 3 months was admitted to our hospital. She had undergone an operation due to a mass lesion of the first rib compressing the thoracic outlet which was detected in the preoperative examinations. During the intraoperative examination it was decided that the lesion was a hydatid cyst and the first rib was totally resected.

CONCLUSION

This report shows that hydatid disease should be taken into consideration amongst the tumoral diseases of the first rib as a very rare cause of thoracic outlet syndrome.
