title: Perihepatitis with pelvic inflammatory disease (PID) on MDCT: characteristic findings and relevance to PID.
abstract: BACKGROUND
  To evaluate the prevalence and image characteristics of perihepatitis, as well as the relationship with some computed tomography (CT) manifestations of pelvic inflammatory disease (PID).
  
  
  METHODS
  Between January 2006 and December 2007, 93 consecutive patients examined with three-phase abdominal CT scans and clinically diagnosed and treated for PID were included. Three radiologists retrospectively reviewed CT scans with consensus, and examined the location (12 areas) and thickness (four grades) of enhancement of the hepatic surface. Several CT manifestations of PID were also evaluated and statistical analysis was performed to determine the relationship of these findings.
  
  
  RESULTS
  Out of the 93 patients, 55 (59%) showed enhancement of the hepatic surface. The right anteroinferior hepatic surface was the most common site (89%) and lower hepatic division showed thicker parenchymal enhancement. Oophoritis (P = 0.020) and extension of mesenteric infiltration (P < 0.001) were revealed as statistically significant factors associated with the presence of perihepatitis in PID.
  
  
  CONCLUSIONS
  Perihepatits commonly occurs in PID; 59% of PID patients in this study had perihepatitis. The predominant site was the right anteroinferior hepatic surface. Perihepatitis seems not to be associated with various CT findings of PID reflecting disease severity, except oophoritis and upper extension of mesenteric infiltration.
