“…However, some studies have succeeded in quantifying fatty pancreas using similar methods and modalities as those used in assessing the liver [19,26,27] . Fatty infiltration of an organ is observed as a decrease in CT attenuation [28,29] . Using this characteristic, Kodama et al [18] examined the degree of fatty change in livers using both unenhanced and contrast-enhanced CT.…”

Background: We suspected that fatty pancreas, accompanied with metabolic syndrome, may be associated with the incidence of postoperative pancreatic fistula (POPF) after radial gastrectomy. Methods: Between February 2012 and March 2014, we reviewed consecutive 79 gastric cancer patients who underwent radical gastrectomy. To quantify the degree of fatty infiltration to pancreas by preoperative contrast-enhanced CT, we measured ratios and differences between pancreatic and splenic attenuation values (P/S and P-S, respectively). The optimal cut-off values of P/S and P-S for predicting POPF were determined using the receiver operating characteristic (ROC) curve analysis. Risk factors for POPF of International Study Group on Pancreatic Fistula grade B or higher were examined using univariate and multivariate analyses. Results: POPF occurred in 6 patients (7.6%). ROC curve analyses revealed that the most optimal predictive values of P/S and P-S were 0.74 and -28.8, respectively. Univariate analysis demonstrated that high visceral fat area (p = 0.037), low P/S (p = 0.013), and low P-S (p = 0.006) were significant risk factors of POPF. Multivariate analysis demonstrated that low P/S (OR 10.2 [p = 0.046]) and low P-S (OR 13.2 [p = 0.023]) were significant risk factors of POPF. Conclusion: Fatty pancreas is a risk factor of POPF after radical gastrectomy.

“…Radiological examination suggests the possible diagnosis, and the best definitive diagnostic procedure is CT, which demonstrates a proliferation of homogenous adipose tissue in the lower abdominal cavity (18, 19). The CT number reading provides information about the nature of the lesion, and the density of the fatty mass with attenuation values between -80 and -120 HU, which is identical to that of subcutaneous fat, may lead to its diagnosis (19).…”

“…The CT number reading provides information about the nature of the lesion, and the density of the fatty mass with attenuation values between -80 and -120 HU, which is identical to that of subcutaneous fat, may lead to its diagnosis (19). When a large mesenteric lipoma extends lower in the abdominal or even pelvic cavity due to its gravity as our case, CT findings of mesenteric lipoma may mimic pelvic lipomatosis, which is a rare condition defined as a nonmalignant overgrowth of normal fat in the perivesical and perirectal spaces (20-22).…”

Giant Mesenteric Lipoma As an Unusual Cause of Abdominal Pain: A Case Report and a Review of the Literature

We report a rare case of giant mesenteric lipoma presenting with colicky abdominal pain. A 29-yr-old woman underwent laparoscopic resection for a giant mesenteric lipoma causing compression of the ileal loop. The resected ileal segment was encased by a giant fatty tissue, and normal mucosal fold patterns of the resected ileum were effaced by the mass. Microscopically, the mass was characterized by homogenous mature adipose tissue without cellular atypia, which was compatible with the diagnosis of a mesenteric lipoma. Despite the benign nature of this tumor, total excision with or without the affected intestinal loop should be considered if intestinal symptoms such as abdominal pain are present.

“…It is more frequently located on the left side of the abdomen, along the jejunal mesentery. The typical location, the aspect, the asymptomatic chronic evolution suggest the diagnosis of mesenteric panniculitis in most cases; however, before the diagnosis is established, all other causes of misty mesentery must be carefully ruled out [8,9].…”

Ultrasound aspect of mesenteric panniculitis. Case report

Mesenteric panniculitis represents a cronic inflammation of the adipose tissue of the mesentery which can present sometimes with the imagistic aspect of one or multiples pseudotumors. We present the case of female patient in which mesenteric panniculitis was found accidentally during a routine abdominal ultrasound examination leading to differential diagnostics problems. Color Doppler and contrast enhancement ultrasonography were helpful for diagnosis evidencing a benign circulatory signal.
