Hepatic Inflammatory Pseudotumor—A Diagnostic Challenge: A Case Report and Review of Literature

Abstract

Inflammatory pseudotumor (IPT) is a rare lesion of unknown origin, characterized by proliferation of fibrous connective tissue and invasion of inflammatory cells. Although benign, it has the propensity to mimic malignant masses given its nonspecific symptoms and imaging manifestations. We present a case of hepatic IPT with variable interpretation on different imaging modalities, called as abscess on computed tomography (CT) and neoplasm on ultrasound and magnetic resonance imaging (MRI), thus posing a diagnostic dilemma. Hence it is important to recognize this as a distinct clinical entity and include it in the differential of liver masses with atypical imaging findings.
