Background Sclerosing mesenteritis (SM) is sometimes used as an umbrella-term for idiopathic inflammatory conditions in the mesentery. Mesenteric panniculitis (MP) is a radiological finding and its relation to clinical SM is not fully understood. The aims of this study were to determine whether any correlation could be found between the radiological findings and the clinical disease course. Methods Patients observed due to idiopathic inflammation of the mesentery were identified. If SM could be verified histologically or MP radiologically, the patients were included in this descriptive retro perspective study. Results Typical radiological changes were observed in 27 patients. A majority (23/27) of these patients had mild to moderate symptoms. This group with typical radiology was labelled MP. Four patients were included due to histologically verified disease but had uncharacteristic radiology involving multiple compartments of the abdomen. All four had marked systemic inflammation, fever and fluctuating radiologic findings. Three had severe disease with multiple hospitalisations and complications but responded promptly to corticosteroids. This group was denoted SM. Conclusions We have identified two subgroups of patients; firstly, MP with stable and characteristic radiologic changes and secondly SM with atypical radiology and a more aggressive clinical course. We propose that the term SM should be reserved for this latter condition.

Sclerosing mesenteritis (SM) is an idiopathic disorder affecting mesentery, characterized by fat necrosis, chronic inflammation and fibrosis. The clinical presentation varies from asymptomatic cases to acute abdomen. The diagnosis is suggested by imaging but can be definitely established only by biopsies. In this paper, we discuss ultrasonography-based management of SM.

Retractile mesenteritis is a rare, fibrosing, inflammatory disease affecting the adipose tissue of the intestinal and colonic mesentery. So far, about 300 cases have been reported in the literature. We present a case of retractile mesenteritis.

Retractile mesenteritis is an extremely rare disease characterised by a non-specific inflammatory and fibrotic process of the mesenteric adipose tissue, which is usually accompanied by pain and a variety of other abdominal symptoms. We describe here the case of a patient with retractile mesenteritis presenting with prolonged high-grade fever and autoimmune haemolytic anaemia without abdominal symptoms. The patient’s illness was complicated by chylous ascites. Diagnosis was suspected by computed tomography and confirmed histologically following exploratory laparotomy. The patient was treated with prednisone and azathioprine, and he had a rapid improvement in anaemia and fever relief, but no substantial change in the mesenteric lesions. Our case adds autoimmune haemolytic anaemia to the wide spectrum of manifestations of retractile mesenteritis and implies the possible involvement of immune mechanisms in the pathogenesis of the disease.
