title: [Computed tomography symptomatology of liver hemangiomas].
abstract: The paper is concerned with analysis of CT-symptomatology of 72 liver hemangiomas in 43 patients. The authors employed standard and dynamic computerized tomography. All hemangiomas were divided into 2 groups: under 6 cm and over 6 cm. Small hemangiomas were characterized by clear-cut contours and regular density. Zones of low density, regular in structure with clear-cut contours were revealed by CT in hemangiomas over 6 cm. Morphologically, this zone corresponded to a hyaline structure (a hyaline slot) making it possible to differentiate hemangiomas from necrotic tumors. In serious cases dynamic CT with visual evaluation and plotting of time-density graphs was recommended. Visually hemangioma had a picture of contrast medium accumulation, beginning from a focal periphery. Graphically the time of appearance of a contrast medium and the time of reaching a maximum for hemangiomas is delayed as compared to the same intervals of contrast medium accumulation in the liver parenchyma. It tells hemangioma graphs from graphs of other tumors, of which intervals coincide with those of liver parenchyma graphs.
