Huge Hepatic Fungal Inflammatory Pseudotumor Misdiagnosed as Primary Hepatocellular Carcinoma

摘要

Fungal inflammatory pseudotumor (FIPT) of the liver is a rare disease that may be mistaken for a malignant tumor. It is difficult to diagnose because of its nonspecific clinical and imaging features. We report the case of a 46-year-old Asian man who presented with a mass in the right upper quadrant of the abdomen. The patient had undergone transcatheter arterial chemoembolization therapy at another institution 6 months earlier, but the mass had continued to enlarge. He had no history of chronic hepatitis B, and the serum a-fetoprotein was negative. Contrast-enhanced ultrasonography and computed tomography images were suggestive of hepatocellular carcinoma. However, ultrasoundguided biopsy revealed features of chronic inflammation. The mass was resected and found to be an FIPT. We discuss the details of the case and review related articles.
