Abstract:
Objective To improve the recognition of the imaging appearances of inflammatory pseudotumors of the spleen (IPS), 3 cases with IPS were reported. Methods The US (n=3), CT (n=3) and MRI (n=1) findings of IPS were reviewed and correlated with the pathologic findings. Results On US, a well-defined solitary mass with heterogeneous echo texture was found in all 3 cases. A hyperechoic rim with associated acoustic shadowing was shown in 1 case. In all of the 3 cases in nonenhanced CT scanning, a well-defined hypoattenuated mass was found. One had a calcified egg-shell-like rim; On the venous/delayed phase of enhanced CT after contrast administration in 2 cases, slight/marked enhancement was shown. On nonenhanced MRI in 1 case, the mass was shown as heterogeneous hypointensity on T1- and T2- weighted images. Conclusion IPS should be included in the differented diagnosis of solitary mass lesion of spleen. The imaging findings depend on the variable proportions of fibrous and granulomatous components within the lesion. IPS was characterized by well-defined solitary mass on sonogram, delayed enhancement on enhanced CT, and hypointensity on T2 weighted MR images.
