CT features of malignant mucinous cystic tumors of the pancreas.

摘要: This study is aimed at evaluating which pre-operative findings CT are prevailingly associated with histologically malignant appearance of mucinous cystic tumor (MCT) the pancreas. The examinations 52 female patients affected pathologically proved MCT were retrospectively evaluated by two radiologists, blinded to histopathological assessment biologic behavior (either benign or malignant). A multivariate logistic regression analysis was performed in order identify most important features nature MCT. Calcifications wall and/or septa, thick wall, and septations resulted malignancy. simultaneous presence all these radiological signs constitutes an almost "certain" marker malignancy, being risk equal 0.95, whereas least them entails a malignancy ranging from 0.56 0.74, according type morphological features. On other hand, absence mentioned negligible (0.02). Mucinous tumors characterized multilocular macrocystic architecture, calcifications present highest advocate prompt surgical intervention. When those absent, probability lower. In this case non-operative management possible.
