ABSTRACT
Hepatobiliary scintigraphy evaluates the biliary clearance of Tc-99m-labeled iminodiacetic acid agents (Tc-99m IDA) and has a high sensitivity and specificity for the diagnosis of acute cholecystitis. False-negative studies are extremely rare. We describe an apparently normal nonmorphine-augmented hepatobiliary study in gangrenous acalculous cholecystitis. Based on clinical findings, computed tomography, and ultrasound demonstration of a dilated gallbladder, a cholecystectomy was performed. Pathologic examination of the gallbladder revealed acute gangrenous cholecystitis with culture positive for Klebsiella pneumoniae.

Endovascular treatment strategies are evolving as viable alternatives for the treatment of aortic pseudoaneurysms. The present report describes an enlarging aortic arch pseudoaneurysm that was successfully treated with a combination of embolization with detachable coils and N-butyl-cyanoacrylate.
