2022

Benign liver lesions are increasingly diagnosed in daily clinical practice due to the growing use of imaging techniques for the study of the abdomen in patients who have non-specific symptoms and do not have an increased risk of hepatic malignancy. They include simple or parasitic cysts and solid benign tumors which differ widely in terms of prevalence, clinical relevance, symptoms and natural history and often lead to significant clinical problems relating to diagnosis and clinical management. Following the need to have updated guidelines on the management of benign focal liver lesions, the Scientific Societies mainly involved in their management have promoted the drafting of a new dedicat…

Review article: intestinal lymphoid nodular hyperplasia in children - the relationship to food hypersensitivity.

2012

SummaryBackground Lymphoid aggregates are normally found throughout the small and large intestine. Known as lymphoid nodular hyperplasia (LNH), these aggregates are observed especially in young children and are not associated with clinical symptoms being considered ‘physiological’. In children presenting with gastrointestinal symptoms the number and size of the lymphoid follicles are increased. Patients suffering from gastrointestinal symptoms (i.e. recurrent abdominal pain) should systematically undergo gastroduodenoscopy and colonoscopy. With these indications LNH, especially of the upper but also of the lower gastrointestinal tract has been diagnosed, and in some children it may reflect …

Spectrum of liver lesions hyperintense on hepatobiliary phase: an approach by clinical setting.

2021

AbstractHepatobiliary MRI contrast agents are increasingly being used for liver imaging. In clinical practice, most focal liver lesions do not uptake hepatobiliary contrast agents. Less commonly, hepatic lesions may show variable signal characteristics on hepatobiliary phase. This pictorial essay reviews a broad spectrum of benign and malignant focal hepatic observations that may show hyperintensity on hepatobiliary phase in various clinical settings. In non-cirrhotic patients, focal hepatic observations that show hyperintensity in the hepatobiliary phase are usually benign and typically include focal nodular hyperplasia. In patients with primary or secondary vascular disorders, focal nodul…

Diagnosis of focal nodular hyperplasia. Role of imaging techniques.

2002

Focal nodular hyperplasia (FNH) is a rare benign liver lesion which is difficult to differentiate from other benign liver pathologies and hepatocellular carcinoma. However, with appropriate new imaging techniques it is, at present, possible to diagnose this lesion with certainty thus avoiding invasive tests. Patient follow-up is also facilitated. It is often incidentally discovered during an abdominal ultrasound for other pathologies. Color power Doppler allows, in most cases, one to distinguish it from other focal liver lesions. However, in doubtful cases contrast-enhanced computed tomography and magnetic resonance imaging can help us to define the exact nature of the lesion. It is only oc…
