“…It is important to diagnose IPT on liver biopsy because it can be cured with medical treatment including nonsteroidal anti-inflammatory drugs, antibiotics or steroids (3). In addition, spontaneous regression or regression after conservative treatment has been reported (1,2,5,7,8). In the present case, we performed fine needle aspiration biopsy of the neoplasm and were able to diagnose it as an IPT.…”

Sonazoid-Enhanced Ultrasonography and Ga-EOB-DTPA-Enhanced MRI of Hepatic Inflammatory Pseudotumor: A Case Report

A liver neoplasm was found in a 63-year-old man with alcoholic liver disease. Sonazoid-enhanced ultrasonography (US) showed that the neoplasm was isoechoic at the early vascular phase and hypoechoic at the post-vascular phase. Gadolinium ethoxybenzyl-diethylenetriamine-enhanced magnetic resonance imaging (MRI) showed that the neoplasm was hypointense at the hepatobiliary phase. We suspected that it was a malignant tumor. By needle biopsy, however, the neoplasm was diagnosed as an inflammatory pseudotumor (IPT). We encountered a rare case of hepatic IPT, the differential diagnosis of which was difficult to distinguish from malignant tumor. Here, we report new US and MRI findings of hepatic IPT.

“…This report well illustrates a common clinical situation of delayed diagnosis of IgG4-RD. Many reports of inflammatory pseudotumor in different sites may be examples of undiagnosed IgG4-RD [ 13 , 14 ]. In the present case, this condition should have been suspected after the histopathological results indicating “chronic inflammatory processes” in the tissue specimens.…”

IgG4-related disease (IgG4-RD) is a recently recognized group of conditions, characterized by tumor-like swelling of involved organs, lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells, variable degrees of fibrosis, and elevated serum IgG4 concentrations. Currently IgG4-RD is recognized as a systemic condition that can affect several organs and tissues. Herein we report the case of a 34-year-old male patient who was admitted to our hospital with diffuse abdominal pain, weight loss, and painful stiffness in his neck. He had a history of tumoral mass of the left maxillary region, right palpebral ptosis with protrusion of the eyeball, and chronic dry cough for about 6 years. Laboratory tests revealed polyclonal hypergammaglobulinemia and increased serum IgG4 levels. Immunohistochemical staining of the maxillary biopsy was compatible with IgG4-RD. He had an excellent response to corticosteroid therapy. This case highlights that IgG4-RD should be included in the differential diagnosis with multisystem diseases.
