Computed tomographic and clinicopathological features of inflammatory pseudotumor of the spleen
1From the Department of Radiology, Sichuan Academy of Medical Science and Sichuan Provincial People's Hospital, Chengdu, Sichuan, China.
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.
