“…Sonographically, often markedly hypoechogenic thickening of the bowel wall is found. Only in early cases is stratification preserved, and in the more advanced cases transmural hypoechogenicity, frequently with massive thickening up to 4 cm, is visualized [96,97,98].…”

Like other cross-sectional imaging methods, transabdominal sonography is increasingly used for evaluation of gastrointestinal diseases. The potentials and limitations of sonography in evaluation of the gastrointestinal tract are discussed. Transabdominal sonography proved to be of clinical value in assessment of appendicitis, diverticulitis, bowel obstruction, chronic inflammatory bowel diseases, intussusception and infantile hypertrophic pyloric stenosis. The sonographic morphology of the most common gastrointestinal diseases is discussed. In experienced hands sonography can be used as primary imaging in several gastrointestinal diseases. The gastrointestinal tract should be included in the sonographic examination of the abdomen, especially if symptoms could be related to the intestine.

Gastrointestinal lymphomas represent 5–20% of extranodal lymphomas and mainly occur in the stomach and small intestine. Clinical findings are not specific, thus often determining a delay in the diagnosis. Imaging features at conventional and cross-sectional imaging must be known by the radiologist since he/she plays a pivotal role in the diagnosis and disease assessment, thus assisting in the choice of the optimal treatment to patients. This review focuses on the wide variety of imaging presentation of esophageal, gastric, and small and large bowel lymphoma presenting their main imaging appearances at conventional and cross-sectional imaging, mainly focusing on computed tomography and magnetic resonance, helping in the choice of the best imaging technique for the disease characterization and assessment and the recognition of potential complications.

“…CT images in arterial (5a), portal (5b) and equilibrium (5c) phases show a voluminous, hypervascularized mass with a progressive ringshaped contrast-enhancement. phomas, with stomach and small bowel being most frequently affected (10) . Primary hepatic lymphomas are extremely rare with less than 100 cases described in the literature (77 cases up to 1999).…”

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
