Imaging features of ciliated hepatic foregut cyst

Figure 1 CHFC in a 30-year-old man. A: Unenhanced CT scan shows a slightly hypoattenuating (47 HU) mass in the medial segment beneath the hepatic surface; B: On enhanced CT scan, a well-defined hypoattenuating mass is revealed with no enhancement; C: On axial T1-weighted imaging, the lesion appears isointense relative to surrounding liver parenchyma; D: Axial T2-weighted imaging shows markedly homogeneously hyperintense mass in the left liver; E: Enhanced T1-weighted imaging delineates slightly hypointense mass just beneath the hepatic surface; F: Photomicrograph reveals a cyst lined by ciliated pseudostratified columnar epithelial cells (HE × 400).
