Abstract
-
PURPOSE: To evaluate the CT features of inflammatory pseudotumor of the liver with histopathologiccorrelation.
MATERIALS AND METHODS
The CT features of 14 cases (ten patients) with pathologically proveninflammatory hepatic pseudotumor were retrospectively analyzed and correlated with resected and biopsy specimens.
RESULTS
The size of lesions ranged between 2.0 and 7.0cm (mean, 3.7cm); On unenhanced CT, the masses were seenas ill-defined hypodense lesions, while on contrast-enhanced CT they were heterogeneous and multiseptated, withenhancement of internal septa and peripheral wall (n=10). In four lesions, central low density and peripheralhomogeneous enhancement were seen. On histopathological correlation, the central hypoattenuated area correspondedto chronic inflammalory cell infiltrates with foamy histiocytes, plasmacytes, and lymphocytes, while thehyperattenuated peripheral wall and internal septa represented dense fibrosis.
CONCLUSION
In patients in whon CTshows a heterogeneous enhancing mass, inflammatory pseudotumor of the liver should be included in differentialdiagnosis.
