title: The correlation of US and CT values in the diagnostics of giant pseudo-cysts of the liver.
abstract: The aim of the study was a comparative assessment of the value of US and CT examinations in the diagnostics of giant hepatic pseudo-cysts. The material comprises 15 cases of complex hepatic pseudo-cysts with diameter exceeding 5 cm, which in 6 cases had traumatic etiology, in 4 neoplastic (cystoadenomas and cystoid adenocarcinomas) and in 5 cases infectious (postinflammatory and parasitic). Considerable disproportions in US and CT pictures of liver cysts were revealed. Posttraumatic cysts showed smooth inner contours in CT while in US irregular contours with thin septa intussuscepting to the inside were found. In 2 cases of neoplastic cysts thin inner septa were only shown with US examination. In parasitic cysts CT visualized only a part of septa visible in US. It was found out that considerable disproportions of US and CT pictures of complex hepatic cysts require combination of both imaging methods in their diagnostics. US shows high sensitivity in revealing septa, determining internal contours and wall thickness. CT reveals calcifications and after contrast enhancement vascularised walls, septa and tissue component. CT is useful in determining topographic relations of big hepatic cysts.
