Abstract
Aim of the study
Inflammatory pseudotumor is a rare benign tumor that can occur at various body sites. Due to its rare occurrence and histological variety radiological data is heterogeneous and limited.
Case description
We present a case of a 71-year-old man with inflammatory pseudotumor of the omentum. Contrast-enhanced ultrasound perfusion pattern showed homogeneous, isoechoic enhancement in the arterial phase with a washout phenomenon in the parenchymal phase, mimicking a peritoneal carcinomatosis.
Conclusions
Inflammatory pseudotumor represents a rare, but important benign differential diagnostic option when considering a malignant disorder. Contrast-enhanced ultrasound is helpful in identifying vital tissue for a targeted biopsy for subsequent histological examination that is essential for the exclusion of malignancy.
