Inflammatory pseudotumor of the liver.

Inflammatory pseudotumor of the liver (IPL) is a rare benign neoplasm. It often masquerades as a malignancy, either primary or metastatic. We describe the case of a 71-year-old man who presented with fever and malaise. Workup revealed a cecal mass, as well as a lesion in the left lobe of the liver. Pathologic examination showed a cecal neoplasm and a hepatic inflammatory pseudotumor. The patient recovered uneventfully. This case highlights the ability of IPL to masquerade as a malignant hepatic neoplasm, and emphasizes the difficulties in diagnosis.
