1/5. Intratumoral steatosis in focal nodular hyperplasia coinciding with diffuse hepatic steatosis: CT and MRI findings with histologic correlation.focal nodular hyperplasia (FNH) is a benign tumorlike condition that is thought to be a hyperplastic response to increased blood flow in an arterial malformation rather than a true neoplasm. Radiologically, FNH usually shows typical findings on unenhanced and enhanced computed tomography (CT) and magnetic resonance images (MRI), with atypical features being the exception rather than the rule. We report an unusual case of FNH with extensive fatty infiltration of the lesion illustrated on CT and MRI and proven by histopathology.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/5. focal nodular hyperplasia of the liver associated with portal vein agenesis: a morphological and immunohistochemical study of one case and review of the literature.Congenital absence of portal vein (CAPV) is a rare malformation. To our knowledge, sixteen cases are reported in western literature. All the cases are associated with other diseases, cardiac malformations (12/17 patients; 16 plus the present case) and hepatic neoplasms being the most frequent observations. We present the case of a girl with a complex malformative syndrome consisting of multicystic kidney dysplasia, CAPV and nodular tumor-like mass of the liver. angiography showed that the splenic vein and superior mesenteric vein joined to form a common trunk directly entering the inferior vena cava above the liver. A review of the CAPV cases of the literature and the clinical and pathological features of the hepatic lesion, classified as focal nodular hyperplasia (FNH), are extensively discussed.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
3/5. A 25-year-old man with a large hepatic tumor and multiple nodular lesions.A 25-year-old man without a prior history of liver disease presented with an 18-cm tumor of the right hepatic lobe, which was associated with multiple nodular lesions in the remaining parenchyma. The histologic and immunohistochemical features of the neoplasm were those of a poorly differentiated leiomyosarcoma with epithelioid features. The nodular lesions measured up to 4 cm in greatest dimension and had gross and microscopic features of focal nodular hyperplasia. This case suggests that multiple focal nodular hyperplasia may occasionally represent a parenchymal reaction to abnormal blood supply developing within the liver as a consequence of an enlarging malignant tumor.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
4/5. focal nodular hyperplasia occurring after blunt abdominal trauma.focal nodular hyperplasia of the liver is a benign neoplasm. The pathogenesis is unknown, but it was hypothesized that focal nodular hyperplasia may be a response to a vascular abnormality. We report on a case of focal nodular hyperplasia that developed in a young patient 1 year after a blunt hepatic injury.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
5/5. Hepatic focal nodular hyperplasia developing in a fanconi anemia patient: a case report and literature review.fanconi anemia, an autosomal recessive and X-linked disorder, is known to be associated with a variety of neoplasms. liver tumors are one of the most frequently observed neoplasms but the association between the two disorders remains obscure. We present a case of a 27-year old female fanconi anemia patient diagnosed with a mass on the right lobe of the liver measuring 90x75x60 mm. Histopathological examination of the mass after right hepatic lobectomy revealed focal nodular hyperplasia. This appears to be the first reported case of a hepatic focal nodular hyperplasia of such proportion associated with fanconi anemia. Previously reported cases of liver tumors in association with fanconi anemia in the English literature were either hepatocellular carcinomas or hepatic adenomas.- - - - - - - - - - ranking = 2keywords = neoplasm (Clic here for more details about this article) |
