Inflammatory pseudotumor of the spleen: report of a case with emphasis on contrast-enhanced ultrasound findings

Abstract

Splenic inflammatory pseudotumor is a rare pathology, and the literature stresses the difficulty of preoperative diagnosis. There are no previous reports of contrast-enhanced ultrasound findings for this tumor in the literature. Our case appears to be the first to be examined using this technique. In our case, contrast-enhanced ultrasound showed the mass to be homogeneously and less enhanced than the surrounding parenchyma in all phases, and it included fine enhanced spots. We also briefly review the literature.

Imaging features and radiologic-pathologic correlations of inflammatory pseudotumor-like follicular dendritic cell sarcoma

“…IPT-like FDCSs of the spleen displayed homogeneous or heterogeneous hypoechoic lesions, consistent with ultrasonographic findings in other studies [ 3 ]. The patchy hyperechoic area detected in the tumor was related to the infiltration of numerous inflammatory cells [ 13 , 14 ]. The abundant strip or short-rod blood flow signals in the periphery, and the circular enhancement around lesions in contrast-enhanced ultrasonography, were consistent with the blood vessel distribution in the pseudocapsule of the tumor in the pathological findings.…”
