Hepatic eosinophilic pseudotumor due to Fasciola hepatica infection mimicking intrahepatic cholangiocarcinoma: A case report

Table 2 Clinical timeline for hepatic eosinophilic pseudotumor misdiagnosed as intrahepatic cholangiocarcinoma

Timeframe	Event
1 month prior admission	Patient presented with recurring upper abdominal pain, fever with chills, and significant weight loss
Week 1	Patient underwent a clinical evaluation and basic laboratory tests, including complete blood count and tumor markers
Week 2	Abdominal CT and magnetic resonance imaging scans revealed a mass in the hepatic hilum, raising suspicion of intrahepatic cholangiocarcinoma
Week 3	Liver biopsies, performed twice, showed no malignant cells but revealed significant eosinophilic infiltration
Week 4	Serologic testing was positive for Fasciola hepatica; treatment with triclabendazole was initiated
6 months later	The patient exhibited marked symptom improvement, weight gain, and complete resolution of the hepatic mass on imaging studies. Furthermore, serologic testing for Fasciola sp. IgG yielded negative results, and stool examinations for parasitic identification were also negative
