Non-neoplastic hepatopancreatobiliary lesions simulating malignancy: can we differentiate?

Abstract

Despite the success of cross-sectional imaging in evaluating hepatopancreatobiliary system malignancies, several nonmalignant disease processes may closely mimic malignancy. Differentiating these benign diseases from malignancy may be difficult, or even impossible, even in the hands of experienced imagers. In this manuscript, we present benign mimics involving the hepatopancreatobiliary system and try to increase awareness of these potential pitfalls.

Hepatic Sarcoid-Like Reaction Mimicking Liver Metastases in a 36-Year-Old Female With Rheumatoid Arthritis

“…Radiologically, hepatic sarcoidosis may be difficult to distinguish from liver metastases and can only be differentiated by a liver biopsy [6][7][8][9]. Contrast-enhanced ultrasound (CEUS) and endoscopic ultrasound elastography are also used tools for detecting abdominal sarcoidosis, mainly hepato-splenic.…”
