  • Title: Intrahepatic abscess due to gallbladder perforation.
    Author: Peer A, Witz E, Manor H, Strauss S.
    Journal: Abdom Imaging; 1995; 20(5):452-5. PubMed ID: 7580783.
    Abstract:
    BACKGROUND: Perforation of the gallbladder with cholecystohepatic communication is a rare cause of liver abscess. We report four cases of this condition and describe the imaging procedures related to its diagnosis and treatment. METHODS: The medical and x-ray files of 39 patients with percutaneous drainage of liver abscesses were retrospectively reviewed. Four patients with hepatic abscess due to gallbladder perforation were identified. The patients presented with clinical features suggestive of cholecystitis. RESULTS: Sonography in four patients showed a hypoechoic lesion in the liver adjacent to the gallbladder. CT in three patients showed a hypodense area in the liver, corresponding to the sonographic findings. Percutaneous abscess drainage, followed by an abscessogram, was performed in all patients. Contrast material injected through the drainage catheter filled the gallbladder directly from the abscess cavity. Two patients subsequently underwent cholecystectomy, confirming perforation of the gallbladder fundus. In both cases the gallbladder was noted to be embedded in the liver and covered by adhesions. CONCLUSION: Perforation of the gallbladder is a rare cause of pyogenic liver abscess. We suggest, however, based on our two patients who underwent surgery, and several cases reported in the literature, that this condition may be more common when the gallbladder is partially or totally intrahepatic.
