Purpose: The aim was to compare computed tomography (CT) findings between patients with mesenteric panniculitis (MP) with and without known malignancy.
Patients and methods: We retrospectively analyzed 116 consecutive patients who were diagnosed with MP on the basis of CT findings and categorized them according to the absence (Group 1: 73 patients) or presence (Group 2: 43 patients) of malignancy. Patient age and sex, diameter, size, mass effect, location, and fat density of the MP mass, presence of a pseudocapsule and/or halo sign, and lymph node status were compared between the two groups.
Results: MP tends to be more common in males, and this trend shows statistical significance when combining the findings for both groups (P=0.041). Patients in Group 1 were significantly younger than those in Group 2 (54.29 vs 64.77 years, P=0.001). A well-defined fatty mass at the small bowel root was observed in all patients. The halo sign was present in most cases in both groups. A pseudocapsule was observed in 36 patients (49%) in Group 1 and 29 (67%) in Group 2 (P=0.045). The average craniocaudal diameter of the MP masses on the sagittal view was 11.14 and 12.5 cm in Groups 1 and 2, respectively (P=0.005). The MP fat density was less negative in patients with malignancy (–66 vs –76 HU, P=0.001). Lymph node status was similar in both groups.
Conclusion: Detailed CT features should be evaluated in patients with MP, as some of these features may indicate an associated malignancy, necessitating further investigation and close follow-up.
