Hepatic Cystic Echinococcosis (Hydatid Cyst) in a Six Year Old.

Presentation To describe a case of cystic echinococcosis (CE) in a previously healthy child and review epidemiology of CE in Ireland. Diagnosis A previously healthy 6 year old girl was found to have a cystic lesion in the right lobe of her liver. Serology for Echinococcus granulosus was positive, and radiological features were suggestive of CE. Treatment The patient was pre-treated with anti-helminthic medications before undergoing a liver segmentectomy to remove the cyst, and received further treatment with albendazole after surgery. Histological findings were consistent with CE due to E. granulosus, likely acquired during travel to continental Europe. Conclusion CE should be considered in the differential of children with asymptomatic cysts in the liver and/or lung, and a travel history elucidated in such cases.
