2/80. Inflammatory pseudotumor of the liver in Kostmann's disease.A case in which inflammatory pseudotumor of the liver (IPTL) seemed to complicate severe congenital neutropenia (Kostmann's disease) is reported. IPTL is a rare entity, especially in childhood. The exact etiology of this lesion is unknown, but it is generally regarded as a benign, reactive inflammatory condition. Based on 15 reported pediatric cases in the literature, the causes, diagnosis, and treatment of IPTL are discussed.- - - - - - - - - - ranking = 3.1868392332943keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
3/80. Inflammatory pseudotumor of the liver in a patient with chronic hepatitis c: difficulty in differentiating it from hepatocellular carcinoma.A case of an inflammatory pseudotumor of the liver in a 75-year-old female with chronic hepatitis c whose radiologic features simulated that of hepatocellular carcinoma (HCC) is presented. On imaging studies, hypervascularity by CO2 ultrasound (US) angiography, enhancement at an early phase and isodensity at a late phase by incremental dynamic computed tomography (CT), perfusion defect by CT during arteriography (CTAP), and clinical background of hepatitis c virus (HCV) infection strongly suggested HCC. A US-guided needle biopsy revealed a mainly diffuse and polyclonal proliferation of lymphocytes positive for leukocyte common antigen (pan-lymphocyte cells), L-26 (B cell lymphocytes), and UCHL-1 (T cell lymphocytes), negative for both kappa and lambda light chains and sparsely distributed neutrophils and histiocytes. No lymphoid follicles were observed. The liver tissue around this tumor showed chronic hepatitis with mild activity and mild fibrosis. These histopathologic findings suggested that the diagnosis of inflammatory pseudotumor of the liver was tenable. As it is difficult to differentiate between inflammatory pseudotumor of the liver and HCC by imaging studies alone, supplemental biopsy, where possible, should be obtained when diagnostic imaging of tumors suggesting HCC is carried out. We emphasize that histopathology is a true gold standard in the diagnosis of this disease.- - - - - - - - - - ranking = 7.960517699883keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |

5/80. association of inflammatory pseudotumor of the liver and Papillon-Lefevre syndrome--case report.A case of hepatic inflammatory pseudotumor mimicking malignancy in a 4-year-old girl with the Papillon-Lefevre syndrome (PLS) is reported. Only recently, an association between this inherited syndrome and liver abscesses has been found. Its possible pathogenesis is discussed and immunologic defects resulting from the Papillon-Lefevre syndrome are presented. The development of inflammatory pseudotumor of the liver might be caused by immunologic disturbances and staphylococcal infection. The picture of the hepatic tumor on imaging in patients with PLS should be attributed rather to inflammatory than neoplastic process.- - - - - - - - - - ranking = 14.321035399766keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
6/80. Inflammatory pseudotumor of the liver with primary sclerosing cholangitis.Inflammatory pseudotumor (IPT) of the liver is a rare benign variant of hepatic masses, and its exact etiology has not been elucidated. We report a case of IPT associated with primary sclerosing cholangitis (PSC). The patient was a 50-year-old man admitted to our hospital because of jaundice. Abdominal ultrasonography (US) and computed tomography showed multiple dilations of the intrahepatic bile ducts and multiple masses in the liver. On magnetic resonance imaging, the masses were slightly hypointense on T1-weighted images and slightly hyperintense on T2-weighted images. On T1-weighted images after the bolus infusion of Gd chelate, the masses had no contrast enhancement, and they were hypointense in the arterial phase and portal venous phase. However, they were slightly enhanced and became almost isointense relative to the surrounding normal liver parenchyma in the delayed phase. Endoscopic retrograde cholangiography demonstrated multiple irregular strictures and dilations of the intrahepatic bile ducts. Angiography demonstrated no abnormal findings, but, interestingly, subsequent dynamic CO2-enhanced US showed a strongly hyperechoic string, indicating that an artery had penetrated through the hypoechoic mass. A US-guided percutaneous needle biopsy revealed that the lesions were morphologically comparable to IPT. After cholangiography and microscopic analysis of the tumor, the final diagnosis was determined to be IPT of the liver with PSC. A number of previous reports have suggested a possible relationship between IPT and PSC, based on pathological findings. This report confirmed, based on clinical findings, that PSC is one of the causes of hepatic IPT.- - - - - - - - - - ranking = 1keywords = pseudotumor (Clic here for more details about this article) |
7/80. Multiple inflammatory pseudotumors mimicking liver metastasis from colon cancer: report of a case.A 54-year-old man underwent an operation for colon cancer histologically diagnosed as moderately differentiated adenocarcinoma with clinical staging of Dukes C. He was prescribed carmofur for adjuvant chemotherapy. A follow-up computed tomography scan done 6 months later revealed two new low-density areas in the liver. A diagnosis of metastatic adenocarcinoma from the previous colon cancer was presumed, based on the patient's history and radiological findings, and resection of the affected area of liver was performed. Histological examination of these tumors revealed that they were inflammatory pseudotumors (IPT). The patient had an excellent postoperative course and has shown no further signs of recurrence in the 3 years since his last operation. IPT of the liver is a rare disease, for which no methods of diagnosis and treatment have been established, since it is difficult to distinguish IPT from hepatocellular carcinoma or metastatic carcinoma. We describe this case with a review of the 101 cases of IPT documented in the Japanese literature, in the hope that it will contribute to the diagnosis and treatment of this unusual disease entity.- - - - - - - - - - ranking = 11.934196166472keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |

9/80. Inflammatory pseudotumor of the liver diagnosed by needle liver biopsy under ultrasonographic tomography guidance.Inflammatory pseudotumor of the liver is a rare benign lesion, but exploratory laparotomy and a hepatectomy are often performed unnecessarily after various misdiagnoses, including liver abscess, hepatocellular carcinoma, metastatic liver tumor, and cholangiocarcinoma. We present a case of hepatic inflammatory pseudotumor in a 17-year-old man in whom diagnosis was confirmed by liver needle biopsy under ultrasonographic tomography (UST) guidance. He had complained of fever and right hypochondralgia 2 months after being operated for appendicitis. He was admitted to our hospital because of the persistence of these symptoms and the presence of a hepatic mass lesion detected by UST. He had hepatomegaly, with tenderness; leukocytosis and elevated erythrocyte sedimentation rate and c-reactive protein level were noted. UST showed a hypoechoic mass in the liver and pre-contrast computerized tomography (CT) revealed a low-density area with an ill defined margin, which was barely enhanced by the contrast medium. On the basis of the patient's clinical symptoms and the laboratory data and imaging studies, the presence of a liver abscess was suspected and antibiotics were administered. One month after the initiation of the antibiotic therapy, UST demonstrated that the portal vein had dilated serpiginously and penetrated into the mass. As the heterogeneous appearance displayed by post-enhanced CT indicated the need for a differential diagnosis of the hepatic mass lesion to rule out hepatocellular carcinoma, percutaneous needle biopsy was performed, under UST guidance. Histopathological examination demonstrated marked infiltration of plasma cells and fibrosis, findings which were consistent with those of hepatic inflammatory pseudotumor. There was a spontaneous reduction of the hepatic pseudotumor without continuous antibiotics and this reduction was documented on follow-up UST and CT.- - - - - - - - - - ranking = 5.9736784665887keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
10/80. Inflammatory pseudotumor of the liver mimicking a malignancy: case report.Inflammatory pseudotumor (IPT) is a rare lesion of the liver that can be clinically indistinguishable from a malignant tumor. A 51-year-old woman was hospitalized for upper abdominal pain and a weight loss of 5 Kg in 2 months. Radiological examination showed a large heterogenous hypervascular mass in the left lobe of her liver, strongly in favor of hepatocellular carcinoma. However, an ultrasound-guided liver biopsy revealed the typical characteristics of IPT, which consist of plump spindle cells with dense inflammatory cell infiltration. A left lobectomy was performed. No microorganisms were found on stained sections. The markedly elevated eosinophil count reverted to normal postoperatively and she remained well on follow-up examination 8 months after discharge. This case exemplifies the difficulty in radiological diagnosis of hepatic IPT and underscores the importance of its histological differentiation from malignancy before laparotomy.- - - - - - - - - - ranking = 1keywords = pseudotumor (Clic here for more details about this article) |
