“…In the three cases, CT images presented quite similar findings of a hypodense mass with ring-shaped contrast-enhancement in association with a clinical picture of fever and pain in the right hypochondrium, suggesting the diagnosis of hepatic abscess that has erroneously led the authors to an attempt of drainage. These lesions presented a subtle, progressive contrast-enhancement on more delayed phases, which has been already described in primary hepatic lymphoma (17) , but that is also identified in other types of lesions (18) . MRI images of one of the patients with primary hepatic lymphoma, demonstrated a hypointense lesion on T1-weighted sequences, heterogeneous hypersignal on T2-weighted sequences, and peripheral enhancement after paramagnetic contrast agent injection, similarly to the findings reported by other authors in the literature (2,6,17,19,20) and considered as non-specific by some authors (6,19) .…”

OBJECTIVE: To describe the main imaging findings of non-Hodgkin's lymphoma presenting as a single liver mass. MATERIALS AND METHODS: A retrospective study was developed with analysis of cases where a single liver mass was observed at ultrasonography, computed tomography and magnetic resonance imaging, and histologically diagnosed as non-Hodgkin's lymphoma. The studies were reviewed by two observers in consensus. RESULTS: Three male patients in the fifth decade of life, with non-specific clinical manifestations and single liver mass diagnosed as non-Hodgkin's lymphoma were identified. A hepatic lesion with target sign was observed at ultrasonography in all of the cases. At computed tomography, all the patients presented a heterogeneous, hypodense mass with a ring enhancement. At magnetic resonance imaging, the lesions were heterogeneous and hypointense on T1-weighted and hyperintense on T2-weighted images. Additionally, a ring enhancement was observed in all of the cases after contrast injection. At the moment of the diagnosis, none of the patients presented lymphadenomegaly or involvement of other solid viscera. CONCLUSION: The diagnosis of hepatic lymphoma should be considered in the presence of a ring-enhanced single liver mass. Keywords: Lymphoma; Liver; Ultrasonography; Computed tomography; Magnetic resonance imaging.OBJETIVO: Descrever as principais características de imagem do linfoma não-Hodgkin apresentando-se como massa hepática única. MATERIAIS E MÉTODOS: Realizamos estudo retrospectivo mediante análise de casos de pacientes com massa hepática única aos exames de ultrassonografia, tomografia computadorizada e ressonância magnética, com diagnóstico histológico de linfoma não-Hodgkin. Esses exames foram analisados por dois examinadores em consenso. RESULTADOS: Identificamos três pacientes, todos do sexo masculino, na quinta década de vida, com quadro clínico inespecífico e que apresentavam massa hepática única e com diagnóstico de linfoma não-Hodgkin. Na ultrassonografia a lesão hepática apresentava-se como massa com aspecto "em alvo" nos três casos estudados. Na tomografia computadorizada observou-se massa hipodensa e heterogênea, com realce anelar em todos os casos. Na ressonância magnética as lesões apresentavam-se heterogêneas, hipointensas em T1 e hiperintensas em T2, e também com realce anelar após a injeção do contraste. Nenhum paciente apresentava linfonodomegalia ou comprometimento de outras vísceras sólidas no momento do diagnóstico. CONCLUSÃO: Na presença de massa hepática solitária e com aspecto "em alvo" deve-se considerar, entre as hipóteses, o diagnóstico de linfoma. Unitermos: Linfoma; Fígado; Ultrassonografia; Tomografia computadorizada; Imagem por ressonância magnética. AbstractResumo

“…PHL lesions appear as hypoattenuating in CT scans, which may have a low-intensity central area with no enhancement following the administration of an intravenous contrast in half the cases, patchy enhancement in 33% of patients and a ring of enhancement in ~25% of cases (3,17,18). Classically, MRI findings in PHL are described as ‘hypointense’ or ‘isointense’ on T1WI, and ‘hyperintense’ on T2WI (3,19). The imaging findings of hepatic lymphoma in the present case were similar to previous studies.…”

Primary hepatic peripheral T-cell lymphoma (PHL) is extremely rare. A case of primary hepatic peripheral T-cell lymphoma of a 59-year-old male is presented in the current study. PHL lesions are diagnosed by the existence of a hepatic mass, in the absence of lymphadenopathy, splenomegaly or bone marrow involvement associated with normal tumor markers. Treatment options are surgical resection and subsequent chemotherapy. Histopathological examination by immunohistochemical staining of the tissue biopsies at laparotomy confirmed a diagnosis of PHL.

“…On MR imaging they present as focal hepatic lesions of various dimensions (from 5 mm to 15 cm), which usually have a low signal intensity on T1-weighted MR images and variable signal intensity on T2-weighted MR images [104,105]. A mild rim of enhancement after intravenous administration of gadolinium-chelate is observed in 60% of lesions [105].…”

Inflammatory bowel diseases (IBD) are associated with an increased risk of gastrointestinal cancers and more specifically in sites affected by chronic inflammation. However, patients with IBD have also an increased risk for developing a variety of extra-intestinal cancers. In this regard, hepatobiliary cancers, such as cholangiocarcinoma, are more frequently observed in IBD patients because of a high prevalence of primary sclerosing cholangitis, which is considered as a favoring condition. Extra-intestinal lymphomas, mostly non-Hodgkin lymphomas, and skin cancers are also observed with an increased incidence in IBD patients by comparison with that in patients without IBD. This review provides an update on demographics, risk factors and clinical features of extra-intestinal malignancies, including cholangiocarcinoma, hepatocellular carcinoma and lymphoma, that occur in patients with IBD along with a special emphasis on the multidetector row computed tomography and magnetic resonance imaging features of these uncommon conditions.
