Inflammatory pseudotumor of the liver is a rare tumor. It has variable clinical presentations and image findings. It can mimic benign or malignant hepatic tumors, and may be difficult to diagnose. We present a case in which a hepatic inflammatory pseudotumor was misdiagnosed as hepatocellular carcinoma because the tumor presented a typical enhancing profile and morphology of hepatocellular carcinoma on computed tomography, and the patient had liver cirrhosis. However, a thicker tumor capsule than that of typical hepatocellular carcinoma was noted while reviewing the computed tomography images. A capsule of inflammatory pseudotumor thicker than that of hepatocellular carcinoma has never been reported in the literature before, and could be an important diagnostic clue to differentiate inflammatory pseudotumor from hepatocellular carcinoma.
肝脏炎性假瘤是一种罕见的肿瘤。它具有多变的临床表现和影像学表现。它可以模拟良性或恶性肝肿瘤，并且可能难以诊断。我们提出了一个病例，由于肿瘤在计算机断层扫描上表现出典型的肝细胞癌增强模式和形态，并且患者患有肝硬化，因此肝炎性假瘤被误诊为肝细胞癌。然而，在回顾计算机断层扫描图像时，注意到肿瘤包膜比典型的肝细胞癌厚。炎性假瘤的包膜比肝细胞癌厚，这在文献中从未有过报道，可能是鉴别炎性假瘤和肝细胞癌的重要诊断线索。
