Mesenteric panniculitis: diagnostic precision.

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.
