title: Ciliated hepatic foregut cyst: case report with an emphasis on US findings.
abstract: Ciliated hepatic foregut cyst (CHFC) is a rare mass, and its medical imaging findings are seldom reported. We present a histologically proven case of CHFC. The patient was asymptomatic, and a mass was found incidentally by sonography (US) in segment IV. The lesion was almost anechoic on fundamental US but filled with dense echoes with distinct posterior echo enhancement on second harmonic imaging. The lesion was avascular on color Doppler US and angiography. Thus, when US detects a mass in segment IV, the possibility of a CHFC should be considered regardless of the US results.
