Management of a ruptured hydatid cyst involving the ribs: Dealing with a challenging case and review of the literature.

INTRODUCTION Hydatid liver cysts can rupture into neighboring structures in 15-60% of patients, and most often involves the bile duct, the bronchi, and the peritoneal/pleural cavities. Rarely, chest or abdominal wall involvement occurs that are challenging to manage. This case report and literature review describes the management of patients with chest wall and rib invasion. PRESENTATION OF CASE A 74-year-old woman, of Spanish origin, presented with right upper quadrant abdominal pain and tender localized swelling. On computer tomography (CT) assessment, the rupture of a hydatid cyst into the right anterior chest wall was identified. Partial involvement of the 10th and 11th rib were noted. The diagnosis was confirmed by a serological test. Surgical treatment involved a radical en bloc right hepatic resection together with resection of the involved ribs, diaphragm and subcutaneous tissue. Primary diaphragm and wall closures were performed. The postoperative course was uneventful with three weeks of albendazole treatment. CT follow-up at six months demonstrated the absence of recurrence. DISCUSSION Complete resection is the gold standard treatment of patients with hydatid cysts with the aim to remove all parasitic and pericystic tissues. CONCLUSION The present report illustrates that an aggressive surgical en bloc resection is feasible and should be preferred for the treatment of hydatid cysts with rupture into the chest wall, even when the ribs are involved.
