Therefore, a fundamental knowledge of the prevalence and image morphology of hepatic hemangiomas, hepatic cysts, focal nodular hyperplasia (FNH), hepatic adenoma, and focal fatty sparing is essential. Zentralbl Chir 123:119123, CAS This condition, called focal sparing, can occur in diverse patterns. Liver areas with reduced focal, rarely zonal accumulation of fat can occur in hepatic steatosis. It was most often found in the 51-60 years age group; the mean age of the patients with focal fatty sparing was 54.9 14.5 years. Furthermore, there are only a few prevalence studies based on CT, MRI investigations, and autopsy studies [11, 12, 15, 16]. Of 269 patients, 76 (28.3%) had steatosis at baseline. (2010) Prevalence and risk factors of focal sparing in hepatic steatosis. On the other hand, focal sparing in a diffusely fatty liver can be observed most frequently around the gallbladder bed, and its most common shape resembles a spot, band or ring (6).

Mechanisms of NAFLD development and therapeutic strategies. In conclusion, the present case was difficult to diagnose because the tumor was hidden within the area of focal sparing, and dynamic contrast enhancement techniques, including CTA, CTAP and dynamic MRI, were useful for diagnosis.

Prevalence of hepatic steatosis in an urban population in the United States: Impact of ethnicity. The remaining 193 patients who did not have fatty liver at baseline were further divided by whether they received curative chemotherapy (, The characteristics of the two patient groups are outlined in, We found that 52 of 135 patients (38.5%) who received adjuvant chemotherapy developed steatosis within one year of follow-up, compared to 14 of 58 patients (24.1%) who did not receive chemotherapy (Relative Risk [RR] 1.57, 95% confidence interval [CI] 0.89 to 2.79) after adjustment for sex, BMI, type 2 diabetes mellitus, hyperlipidemia, and steroid use. It is a spectrum of disease, ranging from hepatic fat accumulation without inflammation to steatohepatitis, fibrosis, cirrhosis, and end-stage liver disease. ; Katirtzoglou, N.A.

The present case revealed a wedge-shaped area with an almost linear boundary and did not show a mass effect in the non-enhanced CT and MR sequence, including chemical shift images. ; Cohen, J.C.; Grundy, S.M. ; Brett, E.M.; Garber, A.J. Here, we observed that there is a trend towards a higher rate of CAS development within one year of follow-up among stage IIIII CRC patients who received chemotherapy compared to the no treatment group. There was also a hypoechoic mass in segment 6 of the liver measuring, 4.8 3.1 cm. 1. Oncol. The most common site of these pseudo lesions are hepatic segments IV and V, the gallbladder bed, the falciform ligament region, and ventral to the portal vein. The relative risk of developing steatosis was not significantly different regardless of statin therapy status at the time of adjuvant chemotherapy (RR 0.45, 95% CI 0.10 to 2.75) after adjusting for sex, BMI, type 2 diabetes mellitus, and hyperlipidemia (, In the present study, the adjusted relative risk of adjuvant chemotherapy reflected a moderately increased risk of steatosis, although the confidence intervals were wide. Moertel, C.; Fleming, T.; Macdonald, J.; Haller, D.G. CT-supported studies have reported the highest figures for prevalence [15, 19]. Through the division into four different genotypic subtypes, new aspects have emerged concerning prevalence and clinical presentation. In rare cases, focal fatty sparing has also been described in other liver segments where, in the first instance, it is generally difficult to distinguish from malignant lesions and can hence pose considerable problems for a differential diagnosis [2426].

These conclusions have critical implications on the quality of life and hepatic function of patients not only in the curative setting, but may also be applicable in the setting of treatment of metastatic disease, in particular in context of patients requiring liver resections for metastases in addition to indefinite metastatic treatment which may require up to 60 cycles of 5-FU-based chemotherapy. Results that were incomplete or ambiguous were excluded from this study. (2009) Contrast-enhanced ultrasound (CEUS) for the characterization of focal liver lesionsprospective comparison in clinical practice: CEUS vs. CT (DEGUM multicenter trial). We often found a high attenuation region around the gallbladder bed in the fatty liver patients on CT examination. 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). (2012) Prevalence of non-cardiac pathology on clinical transthoracic echocardiography. Focal sparing shows oppsite patterns on US and CT: decreased echogenicity on US images and high attenuation on CT images. When located in characteristic locations then there is usually little difficulty in making the correct diagnosis. The prevalence of FNH was 0.2% (n=81).

Del pilar fernandez M, Bernardino ME. ; Tanimoto, A.; Baba, Y.; Zhao, L.; Chen, J.; Middleton, M.S. Our figure of 0.18% is markedly lower than the data published to date. Conclusions The findings of this study suggest that focal fatty sparing usually does not arise in preexisting nonalcoholic diffuse homogeneous fatty liver, and a newly emerging abnormality is more likely a true lesion. It is likely to have different pathogenesis than non-alcoholic steatohepatitis which is a diffuse process. ; MacFarlane, P.W.

Changes in the Prevalence of hepatitis C virus infection, nonalcoholic steatohepatitis, and alcoholic liver disease among patients with cirrhosis or liver failure on the waitlist for liver transplantation. Medical oncologists at St. Michaels Hospital in Toronto, Canada, anecdotally observed that CRC patients receiving adjuvant chemotherapy appeared to develop fatty liver at a higher rate than expected when seen in follow-up, based on imaging. Non-enhanced CT demonstrated a fatty liver associated with a wedge-shaped hyperdense area which occupied almost all of the anterior segment of the right lobe (Fig. To date, only a few studies have been published on the prevalence of focal fatty sparing or of focal fat distribution disorders in the liver [8, 27]. no financial relationships to ineligible companies to disclose. 3). It was suggested that this fibrotic liver tissue corresponded to the area of focal sparing seen on CT and MR images. The examinations were evaluated for the presence of a focal area of increased attenuation in the liver in locations where focal fatty sparing typically occurs: adjacent to the gallbladder fossa and in the medial segment of the left lobe near the porta hepatis.

The most commonly recorded lesion, with a total prevalence of 6.3% (n=2839), was focal fatty sparing, followed by hepatic cysts with 5.8% (n=2631). As was already put forward as a possible explanation in the case of FNH, this could be due to the age of the study participants, the size of the patient population investigated, and the improved differentiation possibilities of modern ultrasound equipment. ; Congdon, L.; Edwards, K.L. The dynamic contrast enhancement techniques, CTA and dynamic MR imaging, showed irregular enhancement in the abnormal area, which indicated disappearance of the normal vessel structure and was quite useful for diagnosing the metastatic tumor. 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]. The mean age of patients at the time of the investigation was 5618.1years (range: 4months105years). In the past 10years, comparatively few ultrasound-based studies have appeared on this subject [69].

A characteristic location for focal hepatosteatosis is the medial segment of the left lobe of the liver ( segment 4) either anterior to the porta hepatis or adjacent to the falciform ligament 1. CAS was determined through a review of radiology reports, and images were reviewed by a single radiologist to maximize inter-rater reliability. A Feature Published values for the prevalence of hepatic hemangiomas range from 0.1% to 20.0% [6, 7, 10, 11] and those for hepatic cysts from 0.06% to 17.8% [7, 9, 10]. This study sought to examine hepatic steatosis, an increasingly recognized health concern worldwide. Glucocorticoids and non-alcoholic fatty liver disease. Focal gallbladder wall thickening (differential). The prevalence of FNH lies between 0.8% and 3.2% [1215], of hepatic adenoma from 0.4% to 1.5% [11, 12, 15, 16], and of focal fatty sparing between 7.2% and 19.8% [8, 17, 18]. Of the remaining 193 cases, patients receiving adjuvant chemotherapy (, Hepatic steatosis is characterized by the infiltration and accumulation of triglyceride within the liver parenchyma [, There is currently no approved pharmacologic treatment for hepatic steatosis, whether metabolic syndrome- or drug-induced. Other variables included clinical data pertaining to their cancer and variables that may influence steatosis development, such as tumour location, whether primary surgical resection was performed, pelvic radiation status, steroid use, statin use, alcohol consumption, and duration and type of adjuvant chemotherapy received.

Prevalence of benign focal liver lesions: ultrasound - Springer There are no ultrasound studies on the prevalence of hepatic adenoma within a large patient population. 1. Macroscopic observation of the sliced resected specimen showed that the tumor was elliptic and not encapsulated, measuring 6.0 x 5.5 x 5.0 cm. 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]. Parts of this manuscript were presented at the Ultrasound Dreilndertreffen 2008, Davos. Baseline and .

Multiple liver pseudotumors due to hepatic steatosis and fatty sparing The diagnosis of FNH was confirmed primarily by CEUS. These findings imply that if differentiation between focal fatty sparing and a tumor is undetermined and follow-up is performed, should any change occur, then an abnormality that is no longer appreciable at follow-up is probably focal fatty sparing rather than a true tumor.
