title: Computed tomographic and clinicopathological features of inflammatory pseudotumor of the spleen.
abstract: OBJECTIVE
  Our goal was to elucidate the computed tomographic (CT) and clinicopathological features of inflammatory pseudotumor of the spleen.
  
  
  METHODS
  Computed tomographic findings and clinic materials of 4 patients with inflammatory pseudotumor of the spleen were reviewed and compared with pathologic findings.
  
  
  RESULTS
  Abdominal contrast-enhanced CT revealed a hypodense mass in the spleen with slight enhancement in the arterial phase in 3 cases. The enhancement persisted with venous phase and was moderate in the delayed phase. The remaining 1 case was a huge mass in the spleen with multiple areas of patchy necrosis and abundant tortuous vessels.
  
  
  CONCLUSIONS
  Inflammatory pseudotumor of the spleen is a rare benign process with nonspecific CT features. The mass was generally hypodense with delayed enhancement on CT.
