Abstract:
Mesenteric panniculitis is an inflammatory process of the adipose tissue of the mesentery. It produces a thickening of the mesentery of the small bowel or colon and can occasionally involve the retroperitoneum. It is characterized by an infiltration of lipid-laden macrophages and associated with variable degrees of inflammation and fibrosis. Several treatments have been used, including colchicine, dapsone, corticosteroids associated or not with immunosuppressants, but there are no prospective controlled studies to define appropriate treatment: moreover, there are cases of regression without specific therapy. We present the case of a patient with mesenteric panniculitis affecting the colon and retroperitoneal space including the right ureter and iliac vein. Immunosuppressive treatment with monthly intravenous pulse cyclophosphamide and oral corticosteroids, resulted in the disappearance of the abdominal mass without relapse during ten months of monitoring.
Insights
Mesenteric panniculitis, a rare inflammatory condition, can affect the abdomen. This case study shows successful treatment of a severe case with immunosuppressive therapy, leading to complete remission.
Area of Science:
- Gastroenterology
- Pathology
- Immunology
Background:
- Mesenteric panniculitis is a rare inflammatory condition affecting the abdominal adipose tissue, leading to thickening of the mesentery.
- Characterized by lipid-laden macrophages, inflammation, and fibrosis, its treatment lacks standardized protocols.
- Existing treatments include colchicine, dapsone, and corticosteroids, with some cases resolving spontaneously.
Observation:
- A patient presented with mesenteric panniculitis involving the colon and retroperitoneal space, including the right ureter and iliac vein.
- The abdominal mass significantly impacted adjacent structures.
Findings:
- Treatment with monthly intravenous pulse cyclophosphamide and oral corticosteroids led to complete resolution of the abdominal mass.
- The patient remained relapse-free during a ten-month follow-up period.
Implications:
- This case highlights the potential efficacy of immunosuppressive therapy, specifically cyclophosphamide and corticosteroids, for severe mesenteric panniculitis.
- Further research into standardized treatment protocols for this condition is warranted.
- Successful management can prevent complications and improve patient outcomes.
