Predicting portal venous anomalies by left-sided gallbladder or right-sided ligamentum teres hepatis: A large scale, propensity score-matched study

Figure 5 Contrast-enhanced computed tomography images of a 39-year-old man with right-sided ligamentum teres and left-sided gallbladder: Axial, maximum-intensity projection with oblique coronal multiplanar reformation. A: The cholecystic axis of the gallbladder (dotted line) is located left to the umbilical fissure and right-sided ligamentum teres (RSLT, arrow); B: Right paramedian portal pedicle (P_RPM) forms the right umbilical portion of the portal vein (asterisk) and joins the RSLT (dotted line). The RSLT is located right to the middle hepatic vein (MHV); C: Portal vein ramification of the Shindoh’s independent right lateral type[2]. P_RPM shares a trunk with left lateral portal vein and forms the right umbilical portion of the portal vein (asterisk) before joining the RSLT (dotted line), which is located right to the MHV. P_RPM: Right paramedian portal pedicle; P_LL: Left lateral portal vein; MHV: Middle hepatic vein; MPV: Main portal vein; RHV: Right hepatic vein; LPV: Left portal vein.
