According to the latest guidelines on contrast-enhanced ultrasound, hypoenhancement of solid lesions in the portal and late phases corresponds to the wash-out phenomenon that characterizes malignancies. IPT may show rapid arterial enhancement and portal or late phase hypoenhancement, falsely suggesting malignancy. We report a case of a diagnostic error in which a multifocal IPT was misdiagnosed as hepatic metastases. The IPT developed after an endoscopic retrograde cholangiography was investigated by close follow-up with CEUS and contrast-enhanced CT.
