The statistical calculations were carried out using the statistics software SAS 9.2 (SAS Institute Inc., Cary, North Carolina, USA) and the data evaluated using descriptive statistics. Fat accumulation is one of the most common abnormalities of the liver depicted on cross-sectional images.

Rofo 173:424429, Massironi S, Branchi F, Rossi RE, et al. NAFLD is considered the hepatic manifestation of metabolic syndrome and is associated with obesity, dyslipidemia, and type 2 diabetes mellitus. The understanding of hepatic adenoma has changed fundamentally in recent years [32, 33]. It is therefore difficult to compare the various study results and apply them to routine ultrasound primary diagnostics. Overall, more adenomas were diagnosed in the younger patient groups under 50years of age than in the older ones. Case of Liver Metastasis from Colon Cancer Masquerading as Focal The size and age structure of the respective study populations, as well as the quality of the ultrasound equipment used, need to be considered here.

In addition, many studies on the prevalence of benign space-occupying lesions of the liver were conducted in the 1990s or earlier, i.e., at a time when the image quality of the ultrasound devices used was greatly inferior [17, 2123].

Vlachou, Raissa Dzulynsky, Amy Di Tomaso, Haider Samawi, Nancy Baxter, and Christine Brezden-Masley. The calculated prevalence of benign focal liver lesions shows that on the fortuitous discovery of space-occupying lesions of the liver, first consideration should be given to focal fatty sparing, simple hepatic cysts and hemangiomas.

There are no ultrasound studies on the prevalence of hepatic adenoma within a large patient population. Focal fatty sparing of the liver is the localized absence of increased intracellular hepatic fat, in a liver otherwise fatty in appearance i.e. The authors declare no conflict of interest.

You may want to read more about NASH here: https://patient.info/health/non-alcoholic-fatty-liver-disease Most hepatic cysts were found in the oldest patients, with a frequency of 38.5% (n=1012). This distribution is the same as that seen in focal fatty sparing and is thought to relate to variations in vascular supply. Idilman IS, Ozdeniz I, Karcaaltincaba M. Hepatic Steatosis: Etiology, Patterns, and Quantification. Hepatocellular carcinoma in the absence of cirrhosis in united states veterans is associated with nonalcoholic fatty liver disease. Features include: inability to visualise the portal vein walls (as the parenchyma is as bright as the wall), decreases by 1.6 HU per mg of fat in each gram of liver, liver and spleen should normally be similar on delayed (70 seconds) scans, earlier scans are unreliable as the spleen enhances earlier than the liver (systemic supply rather than portal), MRI is the imaging modality of choice in any case where the diagnosis is felt to be less than certain. Apart from 2 exceptions, all diagnosed adenomas were solitary findings (89.5%, n=17). Furthermore, there is currently a lack of medical treatment for any population affected by steatosis, regardless of etiology, although a recently published population-based study suggests that statins may confer protective benefits against the development of steatosis.

As regards the age distribution, the respective age-specific prevalence began with 7.0% (n=115) in the youngest patients and rose to a maximum of 22.5% (n=369) of all discovered hemangiomas in the age group between 51 and 60years.

This study sought to examine hepatic steatosis, an increasingly recognized health concern worldwide. Hepatic steatosis is a benign condition characterized by diffuse or focal fatty infiltration of the liver parenchyma. Moertel, C.; Fleming, T.; Macdonald, J.; Haller, D.G.

We often found a high attenuation region around the gallbladder bed in the fatty liver patients on CT examination. It is mostly idiopathic but it has been often related to obesity, diabetes mellitus, alcohol use, hepatitis, starvation, steroid therapy or parenteral nutrition [].The degree of the fatty infiltration can be focal, diffuse or patchy []. in 2005, there has been some research on the association between steatosis and anti-tumour drugs, although the precise impacts of CRC chemotherapy have largely been unexplored.

Pathological examination revealed fibrotic liver tissue adjacent to the tumor; this fibrotic tissue contained fewer fat vacuoles than the rest of the liver parenchyma. Patients had consecutively presented from January 2003 to November 2013 and had undergone abdominal ultrasound for a variety of diseases or for preventive medical examination in the university hospital. The study was conducted in accordance with the Guidelines of the Declaration of Helsinki and the recommendations of Good Clinical Practice. ; Lorimer, A.R. In our study cohort, we did not observe a significant difference in the risk of developing steatosis when comparing patients receiving oxaliplatin-containing chemotherapy compared to those on a 5-FU based regimen (RR 0.64, 95% CI 0.30 to 1.38) after adjusting for sex, BMI, type 2 diabetes mellitus, hyperlipidemia, and steroid use (, The demographics of 135 patients who were treated with chemotherapy were summarized based on statin administration status, shown in, Among patients who were on statins at the time of their adjuvant chemotherapy, 11 of 37 (29.7%) patients developed steatosis within one year; however, 41 of 98 (41.8%) patients who did not receive statin treatment developed steatosis. permission provided that the original article is clearly cited.

Our prevalence figure of 3.6% for hemangioma lies in the mid-range compared to the previously published results from ultrasound-based studies [6, 7, 9, 17]. Of these patients, 103 individuals were treated with an oxaliplatin-containing regimen, which is FOLFOX. Terminology Alcoholic fatty liver may be accompanied by inflammation and necrosis (alcoholic hepatitis) and permanent damage in the form of cirrhosis. Imaging modalities included contrast-enhanced abdominal CT, abdominal ultrasound, and liver or abdominal MRI. The prevalence figures of the two ultrasound-based studies for FNH were 0.8% and 1.8% and lie below the figures of between 1.8% and 3.2% reported from CT, MRI, or pathological investigations [1215].

MRI exhibits the highest sensitivity for detecting hepatic lipid infiltration and can detect as little as 5% steatosis in the liver at a sensitivity of 76.790.0% and a specificity of 87.191% [, Another limitation of this study is the relatively small sample size, particularly for the cohort of patients receiving statins. ; Francque, S.; Staels, B. Pathophysiology and mechanisms of nonalcoholic fatty liver disease. The prevalence figures reported in previous ultrasound studies for FNH were 0.8%3.2% and for hepatic adenoma 0.4%1.5% [8, 15, 17, 20]. CT arteriography and dynamic magnetic resonance images were useful for diagnosing this metastatic tumor. Canadian Liver Foundation 2017 [cited 2020 May 24]. The age-dependent frequency of hepatic steatosis and the related prevalence of focal fatty sparing in patients with hepatic steatosis were also determined (Table2). Prevention of coronary heart diseases with pravastatin in men with hypercholesterolemia: West of Scotland coronary prevention study group. Detection of a mass within a fatty liver can be difficult by CT. Irregular fatty infiltration can show a roundish or well circumscribed appearance, and may be solitary or multiple, simulating hepatic masses (25). PubMed (a) CT arteriogrphy discloses irregular enhancement in the anterior segment, as seen on dynamic MR imaging. PubMedGoogle Scholar. (2016) Seminars in ultrasound, CT, and MR. 37 (6): 501-510. There appears to be some relationship between the high density around the gallbladder area and the fatty liver. Comparison of the study results is also difficult, because the studies differ with regard to the selection of the population investigated, the number of individuals investigated, and the diagnostic method used [ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI) or autopsy]. Parts of this manuscript were presented at the Ultrasound Dreilndertreffen 2008, Davos. Our result of 6.3% is below the prevalence figures of Kratzer et al.
