title: Gallbladder abnormalities associated with hypoplasia of the right lobe of the liver.
abstract: OBJECTIVE
  We investigated the gallbladder abnormalities associated with anomalous right hepatic lobes using US, CT, and/or MRI.
  
  
  METHODS
  The patients, four men and four women, ranged in age from 15 to 91 years, with a mean age of 59.5 years. The right lobe was hypoplastic in seven patients and was completely absent in one patient.
  
  
  RESULTS
  The gallbladder was normally positioned in two patients (infrahepatic) and was absent in two patients. The gallbladder was located posterior to the liver in one patient (retrohepatic) and was located below the right hemidiaphragm in two patients (suprahepatic). Gallstones were present in one patient with jaundice and epigastralgia.
  
  
  CONCLUSIONS
  Anomalous position or agenesis of the gallbladder often accompanies hypoplasia of the right hepatic lobe. Gallbladder position could be a good indicator of right hepatic lobe anomaly.
