Costal hydatidosis: management and outcome of five cases

Abstract

The objective of the study was to report our experience in the management of hydatid cyst of the rib. Between December 2001 and December 2009, five patients underwent surgery for costal echinococcosis, among 234 cases of thoracic hydatid cyst managed in our department. They were three males and two females, aged 19-42 years (mean = 32.2 years). Imaging investigations consisted of chest X-ray and computed tomography. All the patients underwent thoracotomy along the arch of the infected rib. Albendazole was administered postoperatively in all cases. The echinococcosis of the rib was primary in 3 cases, and secondary to thoracic localization in 2 cases. It was located on the right side in four patients, on the left one in one patient. The posterior arch was the site of infection in 3 cases, and the anterior arch in 2 cases. The cyst was intact in 4 cases, and the invasion of adjacent structures was found in one case. There were no concomitant hydatid lesions. The resection of the infected rib was total in 2 cases and partial in 3 cases. There was no postoperative mortality or complications. The follow-up ranged from 28 months to 8 years did not show any recurrence. Echinococcosis of the rib is very rare. To avoid complications and to allow the eradication of the disease, the combination of surgery and antihelmentic drugs remains the best therapeutic choice.
