CT Findings of Gallbladder Perforation
Abstract
- PURPOSE
To evaluate the usefulness in diagnosing the gallbladder perforation
MATERIALS AND METHODS
CT scans of surgically proved 11 cases of gallbladder perforation were
retrospectively reviewed. CT findings analyzed were iuminal diameter of GB, GB wall thickness and configuration,
presence or absence of fluid collection in the pericholecystic or intraperitoneal space, and observation of
pericholecystic anatomic structures. All patients underwent cholecystectomy, and surgical findings were also
compared.
RESULTS
The GB was distended in 6 cases(55% with a range of 4.0-7.5cm, mean :5.2cm). GB wall was
thickened in most cases(9/11,82%) with homogeneous(n=7) or inhomogeneous(n=2) enhancement. At the sites
of perforation, focal defect or contour bulging was seen in the GB wall in 3 cases. in 2 cases with gangrene, GB
wall showed loss of normal contour with mottled contrast enhancement. Pericholecystic or intraperitoneal fluid
co11ection was noted in 9 cases(82%), especially in the region of perforation. In all cases, there was evidence of
diffuse infiltration in the pericholecystic space, omenturn or mesentery. Other findings included
cholecy-stoenteric fistula in 1 case, and intrahepatic or intraperitoneal abscess formation in 2 cases.
CONCLUSION
CT is useful in correct diagnosis of gallbladder perforation.
