The inferior accessory hepatic fissure, a coronal or parasagittal fissure through the parenchyma of the posterior segment of the right hepatic lobe, was observed sonographically in 15 of 2000 patients. The fissure was seen as a thin, echogenic membrane stretching downward from the right branch of the portal vein to the inferior surface of the right hepatic lobe. On cadaveric sections, the fissure was an invagination of peritoneum directed laterally and slightly posteriorly from the medial inferior surface of the right hepatic lobe below the porta hepatis. |
