title: CT Differentiation of Female Peritoneal Tuberculosis and Peritoneal Carcinomatosis From Normal-Sized Ovarian Cancer.
abstract: OBJECTIVE
  The purpose of this study was to analyze the computed tomography (CT) features of female peritoneal tuberculosis and peritoneal carcinomatosis from normal-sized ovarian cancer for their differentiation.
  
  
  METHODS
  We analyzed the CT features of 18 female peritoneal tuberculosis and 17 peritoneal carcinomatosis with proven normal-sized ovarian carcinomas. Omental change, mesenteric change, parietal peritoneal thickening, lymph node enlargement, ascites, ovarian CT attenuation, and ovarian capsular change were analyzed.
  
  
  RESULTS
  Heterogeneous parenchymal hyperattenuation and capsular change of the ovary were more frequently seen in cases of peritoneal carcinomatosis than in cases of female peritoneal tuberculosis (P = 0.002, P < 0.001, respectively). There were no statistically significant differences in the other CT features.
  
  
  CONCLUSIONS
  The differentiation of female peritoneal tuberculosis and peritoneal carcinomatosis with normal-sized ovarian cancer by CT may be a diagnostic challenge. Ovarian hyperattenuation and any prominent ovarian capsular change may facilitate the differentiation between these groups.
