overlooked potentially treatable disorder: idiopathic mesenteric panniculitis

Objective:The aim of this study was to determine the prevalence of mesenteric panniculitis [MP] and to describe its clinical characteristics, therapy, and outcome

Subjects and Methods: This retrospective study was carried out among patients with MP based on computed tomography [CT] scans from January 2012 to December 2015. The CT images were reanalyzed by study radiologists to confirm the previous MP diagnosis. Patients were divided into 2 groups, i.e., idiopathic and secondary, based on the presence or absence of associated predisposing factors such as trauma, malignancy, autoimmune disorders, ischemia, or previous ab-dominal surgery. The clinical characteristics of the 2 groups, as well as treatments, were assessed

Results: Among the 19,869 CT scans, 36 patients [0.18%] with MP were identified [i.e., 19 [53%] females and 17 [47%] males]. The median age was 54 years [range 26 - 76]. Twenty-four patients [67%] were categorized into the idiopathic group. Malignancy was the predisposing factor in 8 [22%] of those patients. Furthermore, abdominal pain was the cardinal symptom observed in 22 patients [92%] in the idiopathic group. In the idiopathic group, 15 patients [63%] were treated with antibiotics and 16 [67%] were treated with nonsteroidal anti-inflammatory drugs [NSAID]. One unresponsive patient was treated with colchicine. Symptomatic relief was achieved in all of the treated patients

Conclusion: In this study, a symptomatic idiopathic subgroup of patients with MP did not have any associated disorder. The response to treatment with antibiotics and NSAID was effective in most of the patients. Basedon these findings, anti-inflammatory treatments beyond NSAID and surgery should be reserved for patients who are unresponsive to antibiotics and NSAID

Pancreatic Islet Cell Amyloidosis Manifesting as a Large Pancreas

A 39-year-old female patient presented to our hospital with epigastric pain lasting for two months. Laboratory results showed impaired glucose tolerance. Ultrasonography of the patient showed a hypoechoic, diffusely enlarged pancreas. CT revealed a large pancreas, with multiple calcifications. On MRI, a diffusely enlarged pancreas was seen hypointense on both T1- and T2-weighted images with heterogeneous enhancement after gadolinium administration. A biopsy of the pancreas revealed primary amyloidosis of islet cells. Decreased signal on T1-weighted images without inflammation findings on CT and MRI were clues for the diagnosis.
