Huge echinococcal cyst of the liver managed by hepatectomy: Report of two cases.

INTRODUCTION

Echinococcocal cysts are predominantly located in the right liver. They are usually solitary and asymptomatic, but large cysts can cause compression symptoms.

CASE REPORTS: We report two cases of huge (25cm and 20cm in diameter, respectively) echinococcal cysts located in the left liver, which presented as a large palpable mass causing compression symptoms. Diagnosis was established with CT scan showing a cystic mass with the characteristic daughter cysts and reactive layer (pericystic wall) consisting of fibrous connective tissue and calcifications. Both patients were treated radically with left hepatectomy and had uneventful postoperative course and no recurrence upon follow-up.

DISCUSSION: The treatment of liver echinococcal cysts represent a unique surgical challenge. Even though conservative approaches are less technically demanding, the radical approach with resection has better outcome with less recurrences, when performed by experienced surgeons.

CONCLUSION

Resection rather than drainage is the management of choice for such huge liver echinococcal cysts.
