The aim of this study was to define the imaging characteristics of primary and recurrent @entity674 ( @entity674 ) in computed tomography with respect to the @entity5 size. Computed tomography was performed in 35 @entity1 with histologically confirmed @entity674 and analyzed retrospectively by two experienced and independent radiologist. The following morphologic @entity5 characteristics of primary ( n=20) and ( n=16) recurrent @entity5 were evaluated according to @entity5 size, shape, homogeneity, density compared with liver, contrast enhancement, presence of @entity730 , @entity1066 , @entity292 or distant metastases and the anatomical relationship to the intestinal wall, and the infiltration of adjacent visceral organs. Small @entity674 (<5 cm) showed a sharp @entity5 margin with homogeneous density and structure on unenhanced and contrast-enhanced images, and were characterized by an intraluminal @entity5 growth. Intermediate sized @entity674 (>5-10 cm) demonstrated an irregular shape, inhomogeneous density on unenhanced and contrast-enhanced images, a combined intra- and extraluminal @entity5 growth with @entity146 findings, and infiltration of adjacent organs in 9 primary diagnosed and 2 recurrent @entity5 . Large @entity674 (>10 cm), which were observed in 8 @entity5 and 11 recurrent @entity5 , showed an irregular margin with inhomogeneous density and @entity146 findings, and were characterized by signs of @entity5 such as distant and peritoneal metastases. Small recurrent @entity5 had a similar appearance as compared with large @entity5 . Computed tomography gives additional information with respect to the relationship of @entity674 to the gastrointestinal wall and surrounding organs, and it detects distant @entity3 . Primary and recurrent @entity674 demonstrate characteristic CT imaging features which are related to @entity5 size. Aggressive findings and signs of @entity5 are found in larger @entity5 and in recurrent disease. Computed tomography is useful in detection and characterization of primary and recurrent @entity5 with regard to @entity5 growth pattern, @entity5 size, and varied appearances of @entity674 , and indirectly gives hints regarding dignity and therefore prognostic outcome.
