INTRODUCTION: Inflammatory hepatic pseudotumor (IHPT) is an important benign liver disease because it is difficult to clinically and radiologically distinguish from malignant tumors. PRESENTATION OF CASE: Here, we describe a case of a 67-year-old male patient diagnosed with multiple inflammatory hepatic pseudotumors. The patient had undergone left hemicolectomy for descending colonic cancer (T3 N0 M0 stage IIA) 2 years prior. He underwent segment 6 and segment 7 partial hepatectomy because of suspected liver metastasis...

RATIONALE: The shortage of available donor organs limits the development of liver transplantation. This case-serial study presents a novel way to expand the donor pool by using the other-wise discarded partial liver resection graft with hepatic benign tumor. PATIENT CONCERNS: From 2012 to 2016, 15 patients with hepatic lesions were admitted to our hospital. 12 patients suffered from right epigastric discomfort and 3 patients worried about uncertain diagnosis. INTERVENTIONS: Regular hepatic lobectomy was performed for all patients and after back-table management the resected partial liver grafts were used for patients with end-stage liver disease for liver transplantation...

Fungal inflammatory pseudotumor (FIPT) of the liver is a rare disease that may be mistaken for a malignant tumor. It is difficult to diagnose because of its nonspecific clinical and imaging features. We report the case of a 46-year-old Asian man who presented with a mass in the right upper quadrant of the abdomen. The patient had undergone transcatheter arterial chemoembolization therapy at another institution 6 months earlier, but the mass had continued to enlarge. He had no history of chronic hepatitis B, and the serum α-fetoprotein was negative...

Hepatic inflammatory pseudotumor (IPT)-like follicular dendritic cell (FDC) tumor is a rare neoplasm. We herein report the case of 19-year-old female patient with an IPT-like FDC tumor and summarize 24 cases of hepatic FDC tumors previously reported in the English literature. The patient presented with complaints of abdominal discomfort, without significant laboratory abnormalities, and underwent surgical removal of a hepatic tumor. The resected tumor was 6 cm in the longest diameter and the tumor cells were positive for CD21, CD35 and Epstein-Barr virus (EBV)...

A 50-year-old woman presented with epigastralgia. Computed tomography (CT) of the abdomen revealed a 6-cm well-enhanced mass extending from the left lobe of the liver to the abdominal wall, suggestive of cholangiocarcinoma. Liver and skin mass biopsies did not provide evidence of hepatic malignancy but were rich in plasma cells and sclerotic lesions. Subsequent detection of elevated serum immunoglobulin G4 (IgG4) led to a diagnosis IgG4-related inflammatory pseudotumor (IPT) of the liver. Treatment with systemic corticosteroids resulted in rapid clinical improvement...

BACKGROUND: Beside hepatocellular carcinoma, metastasis, and cholangiocarcinoma, the imaging findings of other relatively uncommon hepatic lesions are less discussed in the literature. Imaging diagnosis of these lesions is a daily challenge. In this article, we review the imaging characteristics of these neoplasms. METHODS: From January 2003 to December 2014, 4746 patients underwent liver biopsy or hepatic surgical resection in our hospital. We reviewed the pathological database retrospectively...

We present the case of a middle-aged woman with antecedents of cholecystectomy and several episodes of resi-dual coledocolitiasis resolved endoscopically. She attended Emergency Services due to a new clinical picture of abdo-minal pain and alteration of hepatic enzymes. Image tests showed lesions that suggested hepatic abscesses without ruling out a malign origin. Given this doubt it was decided to carry out a thick needle biopsy obtaining a diagnosis of an inflammatory pseudotumour of the liver related to IgG4-related disease...

A hepatic inflammatory pseudotumor, which can be misdiagnosed as a malignant tumor, is a relatively uncommon tumor with nonspecific imaging manifestations. As a new diagnostic technique, contrast-enhanced sonography has become increasingly important in the diagnosis of liver focal lesions. Here we present 3 cases of histologically confirmed hepatic inflammatory pseudotumors diagnosed with contrast-enhanced sonography. "Fast-in and centrifugal-out" may be a characteristic contrast-enhanced sonographic enhancement pattern in the diagnosis of hepatic inflammatory pseudotumors, which needs confirmation in further studies...

BACKGROUND: Hepatic inflammatory pseudotumor (IPT) is a rare disease which often mimics a malignant tumor and is therefore often misdiagnosed and surgically resected. Recently, a concept of IgG4-related diseases (IgG4-RD) has been proposed that is becoming widely recognized and includes IgG4-related hepatic IPT. Corticosteroids are widely accepted as the standard treatment. CASE PRESENTATION: A 72-year-old Japanese man, who had been followed for ten years after surgery and chemotherapy for treatment of hilar and lower bile duct cancers, developed intermittent fever and abdominal pain and visited this hospital...

Immunoglobulin G4-related disease (IgG4-RD) in the pancreatobiliary system manifests as sclerosing cholangitis (SC), hepatic inflammatory pseudotumors, and type 1 autoimmune pancreatitis (AIP). The pathology of IgG4-RD involves an inflammatory process and fibrogenic pathway, the combination of which damages the affected organs. Fibroinflammatory injury is characterized by three microscopic findings: a diffuse lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells, obliterative phlebitis, and storiform fibrosis...

Immunoglobulin G4-related disease (IgG4-RD) is a systemic disease involving many organs; it includes IgG4-related sclerosing cholangitis and inflammatory pseudotumor in the hepatobiliary system. Two types of hepatic parenchymal involvement have been reported in IgG4-RD: IgG4-related autoimmune hepatitis (AIH) and IgG4-hepatopathy. Moreover, only three cases of IgG4-related AIH have been reported. Immunoglobulin G4-related AIH is clinicopathologically similar to AIH, except for an elevated serum IgG4 level and heavy infiltration of IgG4-positive plasma cells in the liver tissue...

Fasciola hepatica is a parasite of the class Trematoda. It commonly has been found in developing countries. When it infects humans is characterized by a triad of fever, pain in right upper quadrant and peripheral eosinophilia. We present a 67-year-old female from a rural town of the north of Lima, Peru, it was found abdominal pain, eosinophilia and focal hepatic lesions. For this reason, a hepatic mass was the initial suspicion. The hepatic biopsy was performed and one of the findings was eosinophilia. Fasciola hepatica infection should be considered as part of differential diagnosis in hepatic tumors with eosinophilia when the origin of the patient is from endemic areas of F...

INTRODUCTION: Inflammatory pseudotumor (IPT) of the liver is a rare and benign disease that has a good prognosis. It is often difficult to distinguish IPT from hepatic malignancies, such as hepatocellular carcinoma (HCC), because specific clinical symptoms are absent and the diseases' radiological findings can be similar. IPT is particularly difficult to distinguish from HCC in livers with hepatitis C virus (HCV)-related cirrhosis. We report a case of IPT of the liver that mimicked HCV-related HCC recurrence...

Reported here is the case of a 55-year-old man who had tarry stools for 3 days before he was seen at this Department. The man had weight loss and an intermittent fever for 3 months prior. Histopathology revealed an inflammatory pseudotumor of the liver. This case is reported here along with a review of the literature. Nine days after surgery, the patient passed bright red blood (150 mL) in the stool with no clear trigger. A colonoscopy a month later revealed no abnormalities. This is a rare report of an inflammatory pseudotumor featuring intractable bleeding...

INTRODUCTION: Inflammatory myofibroblastic tumors (IMTs), a rare condition of unknown etiology, have often been reported to be associated with specific infections or malignant tumors. The question of whether IMT themselves are an inflammatory or a neoplastic process is still going on. CASE REPORT: A 57-year-old female patient was transferred to our hospital with ileus caused by a mesenterial tumor. Intraoperatively, the mesenteric mass and the dependent small intestine segment, as well as a suspect hepatic lesion, were resected...

Hepatic inflammatory pseudotumors are uncommon benign lesions. Accurately diagnosing hepatic inflammatory pseudotumor can be very challenging because the clinical presentation and radiological appearances are nonspecific and cannot be certainly distinguished from malignant neoplastic processes. Herein, we present a case of hepatic IPT in an 8-year-old boy who presented to clinic with a 3-mo history of a tender hepatic mass, fever of unknown origin, and 9-kg weight loss. The physical examination was notable for tender hepatomegaly...
