Deceptions in localizing extrahepatic right-upper-quadrant abdominal masses by CT

Eleven patients with various extrahepatic right-upper-quadrant lesions had findings on computed tomography (CT) that strongly suggested intrahepatic location. Diagnostic uncertainties on CT were caused by the large size of these masses (5-12 cm in diameter) and sparsity of retroperitoneal fat planes...

Zusammenfassung:	Eleven patients with various extrahepatic right-upper-quadrant lesions had findings on computed tomography (CT) that strongly suggested intrahepatic location. Diagnostic uncertainties on CT were caused by the large size of these masses (5-12 cm in diameter) and sparsity of retroperitoneal fat planes. Sonography depicted the true location of these lesions more clearly than CT. The complementary role of sonography is stressed.
