Inflammatory pseudotumor of the spleen: Ultrasound and computed tomographic findings

Inflammatory pseudotumor of the spleen is an extremely rare benign lesion characterized by a wide spectrum of nonspecific inflammatory and reparative changes.The ultrasound and computed tomographic (CT) findings of inflammatory pseudotumor affecting the spleen in an asymptomatic patient are reported. The CT scanning revealed a partially calcified mass showing a nonhomogeneous enhancement after contrast injection. After 3 min of bolus administration, an unenhanced central area, which corresponds to a focal area of fibrosis, was demonstrated.
