Résumé
Background The relationship between mesenteric panniculitis (MP), a benign condition involving adipose mesenteric tissue, and malignancy is still being questioned. Purpose To investigate the prevalence of MP and study its relationship with malignancy. To investigate the 5-year outcome of MP patients for the development of malignancy. Material and Methods Retrospective search for MP reviewing 3054 consecutive multidetector row computed tomography (MDCT) scans. Two radiologists in consensus selected the final MP population. For each MP, two subsequent MDCT scans of patients matched by gender and age. Five-year follow-up data regarding cancer occurrence after index MDCT scans were obtained for the MP and control groups. Comparisons between groups were performed using univariate conditional logistic regression. Results A total of 160 patients had at least three of the five MDCT features defining MP. Sixty-four were excluded owing to disease causing mesenteric infiltration or contiguous neoplastic involvement. The final population included 96 MP and 192 control patients. The prevalence of MP was 3.14%. Most cases of MP were discrete (66.7%), 2.1% were marked. In total, 60.4% and 59.4% of MP and control patients, respectively, had cancer ( P = 0.86). There was no significant association between MP score and presence of cancer ( P = 0.06) nor any relationship between the course of associated cancer and MP evolution. In total, 80/96 MP patients and 50/78 control patients without associated cancer had a 5-year follow-up at least. No significant difference between both groups for new tumor occurrence during follow-up was found ( P = 0.15). Conclusion Our results do not suggest that patients with incidentally found MP should be followed up for early detection of a cancer.
