what? - Right hepatic vein
Main lobar fissure - The main lobar fissure separates the right and left lobes
of the liver.
It is visualized sonographically as an echogenic linear structure extending
from the portal vein to the neck of the gallbladder
**landmark for identifying the gallbladder
Falciform ligament - Attaches the liver to the anterior abdominal wall
Extends from the diaphragm to the umbilicus
Separate the right and left subphrenic spaces
Ligamentum venosum - The ligamentum venosum is a remnant of the fetal
ductus venosus. It divides the caudate lobe from the left lobe.
Ligamentum teres - Lies within the falciform ligament, remnant of the fetal
umbilical vein***, courses within the left intersegmental fissure, dividing
the left lobe into medial and lateral segments
Main Portal Vein diameter should not exceed: - 13 mm or 1.3 cm
Hepatomegaly - Etiology: congestive heart failure, inflammatory processes,
polycystic disease, fatty infiltration, biliary obstruction, neoplasm, budd-
chiari syndrome
Sonographic characteristics: Length exceeding 18 cm, Anterior-posterior
diameter exceeding 15 cm

and placenta and excreted through the bile ducts

Septated cystic mass (honeycomb appearance)
Mobile internal echoes (snowflakes)
Cyst containing small cysts (daughter cysts)
Hepatitis - Fatigue, loss of appetite, fever and chills, nausea, nonobstructive
jaundice, marked elevation in aspartate aminotransferase, alanine
aminotransferase and bilirubin
