Abstract
Introduction Mesenteric panniculitis (MP) includes a spectrum of nonspecific fibroinflammatory disorders of unknown aetiology that affects mainly the root of the mesentery. Case Report. A 68-year-old man is incidentally diagnosed with MP during follow-up investigation for a fusiform coeliac artery aneurysm. Four years since the diagnosis, he is completely asymptomatic. After discussing with him and presenting the current evidence, he decided not to proceed with biopsy because the finding was incidental and he is asymptomatic. Moreover, tumour markers were within the normal range. He has been scheduled for annual follow-ups with computerized tomography (CT) scans and tumour markers. Conclusions MP is a rare chronic fibroinflammatory disease with contradictory evidence regarding its definition and management. Watchful follow-ups with CT scan and tumour markers are recommended for asymptomatic patients.

Medicine (Baltimore) 2022; 101:e29143. [PMID: 35512070 PMCID: PMC9276205 DOI: 10.1097/md.0000000000029143] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 02/19/2022] [Accepted: 03/03/2022] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Mesenteric panniculitis (MP) is a non-specific, localized inflammation at the mesentery of small intestines which often gets detected on computed tomography. An association with malignant neoplasms remains unclear. We performed a systematic review and meta-analysis to examine the association of malignancy with MP. METHODS MEDLINE, EMBASE, Web of Science, and Cochrane databases were searched for articles published from inception to 2020 that evaluated the association of malignant neoplasms with MP in comparison with control groups. Using random-effects method, a summary odds ratio (OR) estimate with 95% confidence intervals for malignant neoplasms in MP was estimated. RESULTS Four case-control studies reporting data on 415 MP patients against 1132 matched-controls met inclusion criteria and were analyzed. The pooled OR for finding a malignant neoplasm in patients with MP was 0.907 (95% CI: 0.688-1.196; P = .489). The heterogeneity was mild and non-significant. Also, there was no heightened risk of any specific type of malignancy with MP. Three more case-series with unmatched-control groups (MP: 282, unmatched-controls: 17,691) were included in a separate analysis where the pooled OR of finding a malignant neoplasm was 2.963 (95% CI: 1.434-6.121; P = .003). There was substantial heterogeneity in this group. CONCLUSION This meta-analysis of matched controlled studies proves absence of any significant association of malignant neoplasms with MP. Our study also demonstrates that the putative association of malignancy with MP is mainly driven by uncontrolled studies or case-series.

Abstract
PURPOSE To assess the relationship between MP and coexisting non-neoplastic disorders. METHODS Consecutive abdominal computed tomography (CT) scans of 4674 patients were evaluated retrospectively for CT features of MP between January 2017 and January 2018. Clinical findings of patients were analyzed. Four control patients were selected from our cohort for each MP patient such that they matched for age, gender and CT protocol. Statistical analysis was performed using a t, Mann-Whitney U, χ2, or Fisher's test. RESULTS 976 patients were excluded from the study due to the exclusion criteria and finally, 102/3698 patients were diagnosed with MP (mean age = 57.2 ± 12.5 years, 52% male). On CT, a hyperattenuated fatty mass (120/120), subcentimeter lymph nodes (117/120), congregation of mesenteric vessels (82/120) within the mass, a fat halo sign (28/120) and a pseudocapsule (88/120) were seen at the mesentery.The intra-observer agreement was almost perfect for the fatty mass and lymph nodes and moderate or substantial for other CT features (p < 0.001). The most prominent disorders were metabolic syndrome (MetS) and urogenital diseases in MP (45%, 37%, respectively) and control groups (31%, 26%, respectively). Between groups, no significant differences were found in the history of abdominal surgery, gastrointestinal and autoimmune diseases (p-value range 0.064-0.663); however, significant differences were found in the rates of vascular, urogenital diseases and MetS (p-value range 0.012-0.036). CONCLUSION MetS and urolithiasis were significantly more common in patients with MP than in those without MP. Therefore, there may be a clinically relevant association between these disorders. MetS may be a risk factor for MP and urolithiasis, and treatment of metabolic disorders should be undertaken to prevent these diseases.

Abstract
A 38-year-old woman presented to the emergency department with a history of thoracic pain and anorexia for 1 week. Thoracic CT scan showed bilateral pleural effusion, a thoracentesis was performed revealing a transudate liquid with polymorphonuclears and predominance of eosinophils. After admission, the patient developed abdominal pain and the abdominal CT scan showed densification of the mesenteric fat characteristic of mesenteric panniculitis (MP). The patient went through investigation for secondary causes of panniculitis including infection, neoplasia and autoimmune diseases, and no abnormalities were found. The patient was treated with corticosteroids over a period of 3 months with complete resolution and without any signs of remission or secondary cause of MP. Moreover, the patient remained asymptomatic for 2 years after being discharged, which strengthens the diagnosis of MP that presented with eosinophilic pleural effusion.

Abstract
Mesenteric panniculitis (MP), part of the spectrum of sclerosing mesenteritis, is an often asymptomatic disorder that is characterised by chronic inflammation of abdominal mesentery. We present a case of an 83-year-old woman who presented with proximal muscle weakness and erythematous, photosensitive rash of the face and upper torso and was subsequently diagnosed with dermatomyositis based on skin biopsy, electromyography and muscle biopsy. She had radiographic evidence of panniculitis on CT scan of the abdomen and pelvis for malignancy surveillance, which improved on serial CT scan 3 months after beginning treatment for her underlying dermatomyositis with prednisone and mycophenolate mofetil. Our case highlights that MP can be associated with underlying autoimmune disease. Connective tissue disease could be considered in the differential of MP when other etiologies such as surgery, trauma and malignancy are ruled out.

Abstract
A 65-year-old man had intermittent abdominal pain for the previous 2 years. This pain suddenly became worse with a fever and elevated inflammatory markers. We took a while to diagnose the patient with mesenteric panniculitis (MP). Although imaging findings suggested MP, we needed to rule out other diseases. Choosing a treatment for the patient also took some time and we finally used glucocorticoid to cure the patient.

Abstract
A previously healthy 74-year-old woman was admitted with vespertine fever, tremors, shivers and loss of appetite within the previous month. Blood tests revealed an elevated C reactive protein serum level. Serologies for infection were negative. Blood cultures grew no organisms. Colonoscopy revealed normal findings. CT showed typical findings of mesenteric panniculitis with infiltration of mesenteric fat that was circumscribed by hyperattenuating capsule and contained enlarged homogenous lymph nodes. The histopathological analysis from mesenterium revealed non-specific signs of chronic inflammation. On institution of prednisolone, the clinical symptoms subsided, and we replaced it with azathioprine after 1 month. After 12 months of therapy, the patient remained asymptomatic, normalised the serological inflammatory markers and repeat CT revealed normal mesenteric fat.

Abstract
Objective To evaluate the diagnostic and treatment approaches for patients diagnosed with mesenteric panniculitis. Material and Methods We retrospectively reviewed all patients diagnosed with mesenteric panniculitis between January 2010 and March 2016. We recorded the demographic features, clinical symptoms, laboratory values, radiological methods, treatment approach, and outcomes of the patients. Results We evaluated 22 patients (17 male and five female) with a mean age of 45.8±15.7 years. The most frequent complaint was abdominal pain. The patients' histories included colon cancer (n=1), prostatic cancer (n=2), renal cell cancer (n=1), diabetes mellitus (n=4), and chronic obstructive pulmonary disease (n=1). Laboratory values revealed elevated C-reactive protein levels in 14 patients (43%). Computed tomography was performed in all the patients. Only 10 patients were followed up in the surgical ward, the remaining 12 underwent outpatient treatment. No complication associated with hospitalization or during outpatient follow-up period was observed. Conclusion Mesenteric panniculitis can be successfully treated conservatively without surgical intervention. Clinical doubt is of great importance for diagnosis, and plausible underlying malignancy should be kept in mind.

Abstract
Abstract
Background
Mesenteric panniculitis (MP) is a rare condition that historically has been associated with the presence of malignancy. Paraneoplastic phenomena in general regress with cure and in most cases with treatment of the cancer. This study was undertaken to determine whether MP regressed with cancer treatment and cure.
Methods
This was a retrospective review of a database of all patients with MP confirmed on CT between 2003 and August 2015 at Christchurch Hospital. Patients were categorized as having malignant or non-malignant disease, and follow-up scans were assessed for remission of MP. Patients with malignancy were further categorized as having malignancy cured or not cured.
Results
A total of 308 patients were identified with possible MP; 135 were excluded as radiological appearances were not typical of MP (43 patients) or there was no follow-up CT (92). Of 173 patients (131 men) included, 75 (43·4 per cent) were diagnosed with malignancy. Follow-up imaging showed that 33 patients (19·1 per cent) had remission of MP, whereas 140 (80·9 per cent) had no remission. There was no difference in the rates of MP remission in the malignancy versus no malignancy groups (P = 1·000), or between groups in which malignancy was cured or not cured (P = 0·572). Nor was there any difference in the rates of MP remission in malignancy cured versus no malignancy groups (P = 0·524).
Conclusion
MP does not behave like a paraneoplastic phenomenon. The association with malignancy is most likely an epiphenomenon of the many CT images acquired for staging of cancer.
