RESUMO
A woman in her 20s presented with haematemesis, post-prandial abdominal pain, weight loss and anaemia. Imaging revealed a non-enhancing mass in the retroperitoneal space along the mesenteric plane, encasing the porto-mesenteric vasculature. Endoscopy showed oesophageal varices. She was diagnosed with sclerosing mesenteritis, causing extrinsic compression of the portal vein and superior mesenteric artery. She underwent endoscopic variceal ligation and received prednisolone and tamoxifen. After 3 months, her post-prandial pain improved, and she did not have further bleeding episodes.

Mesenteric panniculitis is rare, usually idiopathic, caused by inflammation of the fatty tissue of the mesentery, especially in the small intestine. The relation between cancer and mesenteric panniculitis is unclear. In some studies, mesenteric pannicullitis precedes cancer diagnosis; on the other hand, some studies suggest no correlations. Immunotherapeutics have a wide range of side effects; virtually, every system and organ in the body can be affected. Herein, we presented a rare case of mesenteric panniculitis in a patient with larnyngeal cancer as a side effect of nivolumab treatment. The patient was presented with nausea and vomiting and diagnosed with intravenous contrast-enhanced computed tomography and fully recovered with corticosteroid treatment. The case report highlights the importance of noticing rarely seen side effects of immunotherapy which can be treated easily with immunosuppressive agents.

Sclerosing mesenteritis (SM), an idiopathic nonneoplastic condition affecting 0.18% to 3.14% of the population, is characterized by chronic fat necrosis, inflammation, and fibrosis most commonly of the mesentery of the small intestine. Sclerosing mesenteritis typically presents in the fifth or sixth decade of life, where patients with a history of abdominal surgery and/or autoimmune disease may be at higher risk. While many patients are asymptomatic, clinical features and complications are related to the mass effect resulting from the inflammation and fibrosis involved in the pathogenesis of SM. When present, common signs, symptoms, and complications include abdominal pain, weight loss, diarrhea, palpable abdominal mass on examination, bowel obstruction, chylous ascites, and mesenteric vessel thrombosis. Although SM was historically diagnosed predominantly by biopsy, current practice has shifted away from this to computed tomography imaging of the abdomen, given the invasive nature of biopsy. However, certain conditions, including mesenteric neoplasia (lymphoma, metastatic carcinoid tumor, desmoid tumor, mesenteric carcinomatosis), can mimic SM on imaging, and if clinical suspicion is equivocal, a biopsy may be warranted for definitive diagnosis. Asymptomatic patients do not require treatment. For patients with pronounced symptoms or complicated SM, the combination of tamoxifen 10 mg twice daily and prednisone 40 mg daily is the first-line pharmacotherapy; no randomized controlled trial of this regimen has been performed. Rarely, surgery may be necessary in cases of persistent bowel obstruction refractory to medical management. Sclerosing mesenteritis has an overall benign course in most cases, but disease progression and fatal outcomes have been reported.

PURPOSE: Mesenteric panniculitis (MP) represents the uncommon, benign and chronic inflammatory disorder affecting the mesenteric adipose tissues. Its etiology, diagnosis and treatment remain unnoticed. Our report focused on shedding more lights on this condition. PATIENTS AND METHODS: Seventeen MP patients were identified by searching the electronic medical record system in the Zhengzhou Ninth People's Hospital using the search terms "Mesenteric panniculitis" from October 2015 to March 2023. All cases were diagnosed with MP through computed tomography (CT). Their clinical features and treatments were analyzed. RESULTS: There were altogether 17 cases enrolled for this analysis. The male to female ratio was 8:9, and the median age at diagnosis was 64 (range: 37-96) years. There were 15 patients (88.2%) showing abdominal pain to varying degrees. The proportions of symptoms of nausea, vomiting and fever were 23.5%, 23.5% and 41.2%, respectively. Neoplastic disease was present in 3 patients (17.6%). Meanwhile, 9 patients (52.9%) had gallstones, 3 (17.6%) had cholecystitis and 1 (5.9%) had gallbladder polyps. Six patients (35.3%) received antibiotics treatment only and 1 (5.9%) received oral antibiotics and prednisone. One patient (5.9%) received antibiotics followed by prednisone treatment, because the symptoms were significantly relieved after antibiotic treatment, while the disease recurred soon after, and the symptoms improved again after prednisone treatment. The abdominal pain in 9 patients (52.9%) was relieved spontaneously. Two patients (11.8%) died, including one due to respiratory failure caused by pneumonia and the other one because of pancreatic cancer with lung and liver metastases. CONCLUSION: MP is a poorly understood chronic inflammatory disease. Patients often have abdominal pain as the main symptom, accompanied by comorbidities in the gallbladder, and the prognosis is usually good after correct diagnosis and treatment, Therefore, the present report aims to promote the awareness among clinicians of patients with non-classic abdominal symptoms, so as to avoid misdiagnosis or missed diagnosis.

Mesenteric panniculitis is a non-neoplastic condition involving inflammation and fibrosis of the small bowel mesentery. We describe a man in his 60s who presented with 3 months of febrile episodes, confusion and weight loss. The diagnosis of mesenteric panniculitis had been established 2 weeks prior based on an abdominal computerized tomography scan. Extensive diagnostic investigations during his hospitalisation were unrevealing, and the symptoms were ultimately attributed to the mesenteric panniculitis. The fevers resolved over several weeks, and no further episodes have occurred since discharge. This case suggests that mesenteric panniculitis merits consideration in the differential diagnosis of fever of unknown origin.

BACKGROUND An 82-year-old woman presented with acute pyrexial illness and mesenteric panniculitis and developed biochemical aseptic meningitis (cerebrospinal fluid pleocytosis with no identifiable pathogen). Investigation determined her illness was likely a delayed hypersensitivity reaction caused by sulfasalazine. Sulfasalazine-induced aseptic meningitis is a rare condition often diagnosed late in a patient's admission owing to initial non-specific illness symptomatology requiring the exclusion of more common "red flag" etiologies, such as infection and malignancy. CASE REPORT An 82-year-old woman with a history of recurrent urinary tract infections and seronegative arthritis presented with a 3-day history of fatigue, headache, dyspnea, and lassitude. On admission, she was treated as presumed sepsis of uncertain source owing to pyrexia and tachycardia. Brain computer tomography (CT) revealed no acute intracranial abnormality. Furthermore, CT of the chest, abdomen, and pelvis did not reveal any source of sepsis or features of malignancy. After excluding infective etiologies with serological and cerebrospinal fluid testing, sulfasalazine-induced aseptic meningitis (SIAM) was diagnosed. The patient was then commenced on intravenous steroids, resulting in immediate defervescence and symptom resolution. CONCLUSIONS SIAM remains a diagnostic challenge since patients present with non-specific signs and symptoms, such as pyrexia, headaches, and lassitude. These patients require a thorough investigative battery starting with anamnesis, physical examination, biochemical testing, and radiologic imaging. This case illustrates the need for a high suspicion index of drug-induced hypersensitivity reaction in a rheumatological patient with pyrexial illness where infective etiologies have been confidently excluded. Prompt initiation of intravenous steroids in SIAM provides a dramatic recovery and resolution of symptoms.

OBJECTIVES: To analyze the computed tomography (CT) findings of idiopathic mesenteric panniculitis and the factors related to its characteristics and to improve the understanding of the disease. METHODS: The imaging findings of 121 patients with mesenteric panniculitis were retrospectively analyzed, along with related factors such as age, sex, and abdominal visceral fat area. RESULTS: Among the 121 patients, two had midgut malrotation, and the lesions were located outside the mesentery on the right side of the abdominal cavity, while the lesions in the other patients were located around the mesentery on the left side of the abdominal cavity, presenting as patchy or patchy fuzzy high-density masses. Annulus fibrosus and/or fatty ring signs were also observed in some patients. Scattered soft tissue nodules were observed around the mesentery in 119 patients. Eight patients had intestinal tract traction and retraction, and one patient had secondary intestinal obstruction. Nearly half of the patients had mesenteric vascular changes, and three had mesenteric vascular thrombosis. Among the 121 patients, there were 89 males and 32 females, aged 22-83, with an average age of 52.14 ± 13.53 years. The distribution range of abdominal visceral fat area (VFA) in 121 patients was 79.85-331.65 cm2. CONCLUSION: Mesenteric panniculitis has certain characteristic imaging findings that can be accompanied by often ignored changes in the mesenteric blood vessels and intestinal tubes. Intestinal obstruction and mesenteric vascular thrombosis are rare complications, and their primary causes are often overlooked. Mesenteric panniculitis was correlated with sex, age, and VFA.

Mesenteric panniculitis is a primary inflammation of the mesentery with variable necrosis, inflammation and fibrosis of the fatty tissue. It can be idiopathic (primary) or secondary (associated) to other diseases, asymptomatic and accidentally discovered or revealed by abdominal pain or complications (intestinal obstruction or peritonitis). We here report the case of a 53-year-old patient, admitted with acute abdominal pain, cessation of the transit of materials and gases, in a febrile context. Patient's history included chronic abdominal pain suggesting König´s syndrome and epigastralgia lasting several years. Physical examination showed sore face and abdominal examination revealed mild bloating, marked tenderness in the right iliac fossa (RIF) and in the periumbilical region, without guarding or rigidity and borygms heard on auscultation and with normal rectal examination. A diagnosis of bowel obstruction and fever was made, with suspicion of meso-celiac appendicitis. Abdominal X-ray without preparation and ultrasound confirmed the diagnosis of bowel occlusion. Exploratory laparotomy revealed functional stenosis of the ileum (König´s syndrome) at 1.20m from the ileocecal junction, with multiple adhesions. Adhesiolysis revealed hyperemic appendix measuring 15cm long, whose anatomo pathological examination showed a mucous membrane with inflammatory infiltrate and a wall rich in polynuclear cells. Infiltration of the ileal mesentery causing color change (reddish and greyish in some areas) and small nodosities with friability and tearing on simple handling led to suspicion of mesenteric panniculitis, then confirmed by anatomopathological examination, showing inflammatory reaction in the fatty tissue specimen with infiltration by macrophages, associated with necrotic patches and degeneration. Treatment was based on bowel emptying, anterograde appendectomy, and a combination of corticosteroid (Dexamethasone 24 mg/day) and chymotrypsin (10000 IU/day). The patient´s outcome was good and he was discharged in the 10th postoperative day. The patient underwent clinical and paraclinical follow-up (3 months) for another unknown associated pathology or a pathology that may have occurred early.

A 67-year-old man with previous cardiovascular disease was referred to our consultation due to a 5-month history of recurrent epigastric pain. Esophagogastroduodenoscopy and full blood workup presented no alterations. CT scan showed an irregularly shaped mass at the root of the mesentery, measuring 40x25x47mm, with spiculated contours and retractile behaviour (a). Simultaneous densification of the adjacent fat and infracentimetric ganglionic formations scattered throughout the mesentery were shown. Surgical biopsy revealed extensive storiform fibrosclerosis, with the presence of interstitial lymphoplasmocytic infiltrate and obliterative phlebitis (b); the plasma cells had mostly IgG expression, with IgG4:IgG ratio >40% (c), accounting for more than 30- 40 IgG4 plasma cells per field. The serum IgG4 level was 137mg/dL. A diagnosis of IgG4-related sclerosing mesenteritis was made, without other organ involvement. Prednisolone (0.6mg/kg/d) improved partially the abdominal pain, so steroid sparing strategy with off-label rituximab was associated. Due to its low prevalence, the understanding of this entity is scarce, and its diagnosis is challenging. Unlike other manifestations of IgG4-related disease, the intra-abdominal disease is identified in later stages, due to unspecific symptoms. This case aims to raise awareness about this condition as a differential diagnosis of abdominal pain.

BACKGROUND: Mesenteric panniculitis is a chronic inflammatory process seen in mesenteric tissue. The purpose of this study was to assess the prevalence, clinical, laboratory, and radiological findings, and malignancy in patients diagnosed with mesenteric panniculitis using computed tomography. METHODS: A total of 716 patients with mesenteric panniculitis were retrospectively evaluated by screening all computed tomography scans performed between January 2005 and December 2018. RESULTS: Among 65 278 patients undergoing CT, 716 were diagnosed with mesenteric panniculitis. The prevalence of mesenteric panniculitis was 1.1%. The mean age was 56 ± 14 (20-91) years. The malignant and nonmalignant groups comprised 354 (49.4%) and 362 (50.6%) patients, respectively. The mean age of the malignant group was significantly higher than the nonmalignant group (P < .001). The most common malignancy was breast cancer (12.2%). A history of abdominal surgery was present in 179 (25%) patients with mesenteric panniculitis and it is higher in the malignant group than the nonmalignant group (128 [36.1%], 51 [14%], respectively, P < .001). Mean hemoglobin level and leukocyte count were lower in the malignant group than in the nonmalignant group (P < .001, P < .001, respectively). The mean erythrocyte sedimentation rate was higher in the malignant group than in the nonmalignant group (P = .030). Radiological criterion 2 was less common and radiological criterion 5 was more common in the malignant group than the nonmalignant group (91.0%, 96.4%, P = .004; 35.9%, 27.1%, respectively, P = .011). CONCLUSIONS: It is recommended to conduct research for malignancy in patients with mesenteric panniculitis, especially in the presence of clinical, laboratory, and radiological findings with high-risk features.

"Retractile mesenteritis" was the first name given to a rare, benign, inflammatory disease that affects the adipose tissue of the intestinal mesentery and less frequently other locations. Now labeled as mesenteric panniculitis, the pathogenic mechanism remains unclear. Several stimuli could be involved, and it is sometimes associated with other conditions such as malignancy or autoimmune diseases. We present a case of mesenteric panniculitis with extensive abdominal and extra-abdominal involvement that developed a few months after SARS-COV2 infection, raising the hypothesis of this virus as a potential trigger for autoinflammatory and autoimmune diseases.

Mesenteric panniculitis is encountered frequently during abdominopelvic CT scanning, often as an incidental finding. The observation is problematic because an association with malignancy has been raised in the literature. This review will describe the CT appearances and examine the available evidence regarding the significance of this finding.Ultimately, the literature remains unclear regarding how these patients should be managed, if at all.
