Current Oncology | Free Full-Text | Evaluation of Adjuvant Chemotherapy 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. 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. Conversely, some cases of true hepatic masses have been reported to mimic fatty infiltration (11) or focal sparing (12).

It was suggested that the tumor caused this ischemia due to intrahepatic portal vein blockade. CT-supported studies have reported the highest figures for prevalence [15, 19]. 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. 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). 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].

Scand J Gastroenterol 50:355359, Dietrich CF, Sharma M, Gibson RN, Schreiber-Dietrich D, Jenssen C (2013) Fortuitously discovered liver lesions. The age-dependent frequency of hepatic steatosis and the related prevalence of focal fatty sparing in patients with hepatic steatosis were also determined (Table2). This distribution is the same as that seen in focal fatty sparing and is thought to relate to variations in vascular supply. Focal Fatty Sparing Usually Does Not Arise in Preexisting Nonalcoholic reported a prevalence of 7.2% in a population of patients with colorectal carcinoma [17]. The purpose of this study was to investigate whether fatty sparing adjacent to the gallbladder fossa is related to efferent blood flow from the gallbladder wall. ; Tomlinson, J.W.

Prevalence of benign focal liver lesions: ultrasound - Springer The prevalence of hepatic hemangioma was 3.3% (n=1640), while that of FNH was 0.2% (n=81) and that of hepatic adenoma was 0.04% (n=19). The prevalence data published so far on hepatic adenoma are between 0.4% and 1.7%.

Chemotherapy-associated steatohepatitis. ; Cohen, J.C.; Grundy, S.M. ; Sada, Y.H. The aim of the study was to determine the sonographic prevalence of benign focal liver lesions on the basis of a population of hospital patients. The authors declare no conflict of interest. ; Syrigos, K.N. For example, the prevalence of hepatic hemangioma determined in the studies ranged from 0.1% to 20.0% and that of hepatic cysts from 0.06% to 17.8%. Since drug-induced hepatotoxicity was described by Grieco et al. Naturally, these cannot be recorded in retrospective ultrasound prevalence studies. This also would account for focal fatty change/sparing sometimes seen related to vascular lesions. In comparison with CT, MRI, and autopsy studies, which show a far higher range of prevalence, our figure is in the lower third [10, 11, 19, 20]. 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]. 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. (2015) Hepatic hemangioma in celiac patients: data from a large consecutive series. Epidemiology CAS 4 and 5). 4).MRI is very useful for making the diagnosis of focal hepatic steatosis, which appears isointense or hyperintense to liver on in-phase images and loses signal on out-of-phase images. The mean age of patients at the time of the investigation was 5618.1years (range: 4months105years). Such atypical cases may simulate neoplasms on CT scans (1,810). Common patterns include diffuse fat accumulation, diffuse fat accumulation with focal sparing, and focal fat accumulation in an otherwise normal liver. Alcoholic fatty liver may be accompanied by inflammation and necrosis (alcoholic hepatitis) and permanent damage in the form of cirrhosis. ; Park, J.Y. Abdom Radiol 41, 2532 (2016).

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].

Focal gallbladder wall thickening (differential) - Radiopaedia This difference can be related to the population size and age of the patients studied [13, 14]. Detection of Hepatic Steatosis on Contrast-Enhanced CT Images An association between the occurrence of benign focal liver lesions and age was observed.

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.

As with hemangioma, there are a comparatively large number of prevalence studies for hepatic cysts, but they also differ in terms of study size, patient populations investigated, and diagnostic techniques used. Our measured mean cyst size of 2.2cm corresponds to the values published in the literature [19, 22, 23, 30]. At least one of the lesions to be investigated was diagnosed in 15.1% (n=6839) of the patients of the total population. ; Finn, J.P.; Stark, D.D. For analyzed and interpreted the data. We often found a high attenuation region around the gallbladder bed in the fatty liver patients on CT examination.

PubMed The prevalence of 0.04% determined by us is considerably lower than that found in the previous studies. Grieco, A.; Forgione, A.; Miele, L.; Greco, A.V. Unusual patterns of hepatic steatosis caused by the local effect of insulin revealed on chemical shift MR imaging. Unfortunately, we cannot compare our results on age and gender distribution or those concerning the average size of the hepatic adenoma with any of the studies available to us. However, few reports described nodular . On sonography, the entire liver showed increased echogenicity, suggestive of fat deposition. Furthermore, there are only a few prevalence studies based on CT, MRI investigations, and autopsy studies [11, 12, 15, 16]. Chemotherapy-associated steatosis is poorly understood in the context of colorectal cancer. The investigating physician is therefore increasingly faced with the problem of differentiating between malignant and benign space-occupying processes and of distinguishing the various lesions from each other [24]. https://doi.org/10.3390/curroncol28040265, Lee, Michelle C.

Chemotherapy-associated steatosis is poorly understood in the context of colorectal cancer. Women were somewhat more affected (56.1%, n=1477) than men (43.9%, n=1154).

Overall, more adenomas were diagnosed in the younger patient groups under 50years of age than in the older ones. Chemotherapy-associated steatosis is pathologically indistinguishable from NAFLD, which has a benign onset as simple hepatic steatosis, but can asymptomatically progress to steatohepatitis [, Despite these risks, current treatment for hepatic steatosis is limited to changes in lifestyle to mitigate cardiovascular risk factors [, In this study, the primary mode of determining steatosis status in patients included a review of the medical records and the abdominal images (CT, ultrasound and MRI) by a single radiologist.
