Hepatic mass caused by Fasciola hepatica: A case report

Fascioliasis is a zoonotic infestation which presents with a wide spectrum of clinical pictures. However, it may often be overlooked, especially in the acute phase, because of uncertain symptoms. Fasciola hepatica can have an initial presentation similar to malignant liver mass or complex hepatic cyst. Here, we report a case of a hepatic mass caused by fasciola hepatica.

A 48-year-old woman came with chief complaints of epigastric and right hypochondrial discomfort associated with nausea and vomiting. Ultrasonography (USG) showed a heterochronic lesion in the segment VIII of the liver with few cystic lesions. CECT abdomen and pelvic gave impression of ill-defined irregular hypodense lesions in the right lobe of the liver with progressive enhancing peripheral and central cystic areas suggestive parasitic liver infestation likely echinococcus alveolaris. Right hepatectomy was done and the patient was discharged without any complications.

Fascioliasis is uncommon in developed countries but more commonly seen in developing countries. The identification of fasciola hepatica eggs in the stool is a standard method for the diagnosis of fascioliasis. Fascioliasis may cause a wide variety of clinical signs ranging from asymptomatic infection to severe liver cirrhosis. Surgery for complex hydatid cysts of the liver is potentially burdened by serious complications. Technique of choice for surgical management remains inconclusive.

Fasciola hepatica infection can mimic a malignant liver mass or a complex hepatic cyst because of its uncertain presentation. The disease can be prevented with public education and environmental precautions.
