Inflammatory Pseudotumor of the Liver—A Rare Entity and a Diagnostic Challenge

Abstract

Inflammatory pseudotumors are rare benign lesions that occur throughout the body. Hepatic pseudotumors are uncommon lesions, accompanied by fever, malaise, abdominal pain, and mass effect, and therefore are commonly misdiagnosed as malignant tumors or liver abscesses. Because even routine imaging procedures usually fail to differentiate hepatic pseudotumors from liver neoplasms, a diagnostic histology procedure is usually needed. We present a case of hepatic pseudotumor that resolved spontaneously and review the literature, including 40 previously reported cases and the differential diagnosis.
