Gallbladder perforation: comparison of US findings with CT.
We compared the ultrasound (US) findings of gallbladder (GB) perforation with computed tomography (CT) in 13 patients with GB perforation confirmed at surgery. The common findings of GB perforation were pericholecystic fluid collection and layering of GB wall on US, pericholecystic fluid collection, streaky omentum or mesentery, and GB wall defect on CT. Pericholecystic fluid collection, layering of GB wall, and cholelithiasis were similarly detected on US or CT. GB wall defect and/or bulging of the GB wall suggested a site of perforation was revealed in five patients (38.5%) on US and nine (69.2%) on CT. CT further disclosed the findings of streaky omentum or mesentery (84.6%). CT was superior to US for diagnosis of GB perforation.
