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

Figure 4 Morphological changes of the hepatic hilum lesion on computed tomography scans post-treatment. A: The hepatic lesion in segment IV was initially suspected to be a biliary tumor; B: Three months after a single dose of triclabendazole, the lesion showed no features of a biliary neoplasm. Only a few small, low-attenuation lesions remained in both liver lobes, with no localization to the hepatic hilum; C: By 6 months post-treatment, the original lesion was nearly resolved, and the gallbladder showed no signs of tumor invasion. ACE: Arterial phase contrast enhanced; Non-CE: Non-contrast enhanced; VCE: Venous phase contrast enhanced.
