Inflammatory pseudotumor is a rare disease, that is regarded as a benign reactive inflammatory process, although its etiology and pathogenesis are still unknown. The liver is one of the organs most frequently involved, but inflammatory pseudotumors have been reported in many other sites in the body. Inflammatory pseudotumor of the liver presents as a solitary or, less frequently, multiple space-occupying lesion, which the common imaging techniques do not clearly distinguish from primitive or metastatic hepatic malignancies. Biopsy of the lesion is therefore necessary for diagnosis. The case of inflammatory pseudotumor described here presented with radiologic features of multiple solid space-occupying lesions in the liver, associated with multiple osteolytic lesions in the ribs. Such an association, very suggestive of malignancy, has not yet been reported for inflammatory pseudotumors. Optimum management of this disease has not yet been standardized. The majority of patients are treated by hepatic resection, although spontaneous regression has also been described. In our case, rapid improvement of both hepatic and costal lesions was observed, although the patient did not receive any specific treatment.

Abstract

Inflammatory pseudotumor is a rare disease, that is regarded as a benign reactive inflammatory process, although its etiology and pathogenesis are still unknown. The liver is one of the organs most frequently involved, but inflammatory pseudotumors have been reported in many other sites in the body. Inflammatory pseudotumor of the liver presents as a solitary or, less frequently, multiple space-occupying lesion, which the common imaging techniques do not clearly distinguish from primitive or metastatic hepatic malignancies. Biopsy of the lesion is therefore necessary for diagnosis. The case of inflammatory pseudotumor described here presented with radiologic features of multiple solid space-occupying lesions in the liver, associated with multiple osteolytic lesions in the ribs. Such an association, very suggestive of malignancy, has not yet been reported for inflammatory pseudotumors. Optimum management of this disease has not yet been standardized. The majority of patients are treated by hepatic resection, although spontaneous regression has also been described. In our case, rapid improvement of both hepatic and costal lesions was observed, although the patient did not receive any specific treatment.
