Abstract
BACKGROUND

Hepatic eosinophilic pseudotumor (HEPT) is a rare condition that mimics malignant hepatic tumors, posing significant diagnostic challenges. This case report highlights the importance of considering parasitic infections like Fasciola hepatica(F. hepatica) in the differential diagnosis of hepatic masses, especially in endemic regions, to prevent unnecessary interventions.

CASE SUMMARY

A 40-year-old female presented with a 1-month history of epigastric pain and significant weight loss. Imaging revealed a hepatic mass, initially misdiagnosed as intrahepatic cholangiocarcinoma. Laboratory results showed marked eosinophilia, and histopathological examination confirmed significant eosinophilic infiltration without malignancy. Serological testing identified F. hepatica infection. The patient was treated with a single dose of triclabendazole, leading to complete symptom resolution and normalization of hepatic imaging findings within days.

CONCLUSION

HEPT due to F. hepatica can closely mimic malignancy; timely antiparasitic treatment is crucial for resolution.

Core Tip: This manuscript presents a case of hepatic eosinophilic pseudotumor (HEPT) misdiagnosed as intrahepatic cholangiocarcinoma, later confirmed to be caused by Fasciola hepatica infection. HEPT, a rare benign condition characterized by dense eosinophilic infiltration, mimics malignant hepatic tumors, posing significant diagnostic challenges. The report emphasizes the importance of histopathological and serological analyses in differentiating HEPT from malignancies, especially in endemic regions. The case demonstrated the efficacy of triclabendazole in resolving HEPT secondary to parasitic infection, highlighting the need for awareness of parasitic causes in atypical hepatic lesions.
