title: Mesenteric fibromatosis masquerading as an ovarian neoplasm twenty years after Chernobyl radiation exposure.
abstract: BACKGROUND
  Since their initial description in 1832, desmoid tumors have been reported to occur in virtually every part of the body. Intra-abdominal desmoid tumors, or mesenteric fibromatosis, are often associated with Familial Adenomatous Polyposis mutation in a syndrome known as Gardner's Syndrome. Although sporadic cases of desmoid tumors do occur, unlike Gardner's Syndrome, they predominantly occur extra-abdominally.
  
  
  METHODS
  Case report of a 61-year-old female who presented with two months of abdominal pain, progressive lower abdominal distension and a 10-15 pound weight gain accompanied by one week of urinary hesitancy and frequency. Patient underwent a diagnostic workup for an ovarian neoplasm, but was found at surgery to have mesentric fibromatosis.
  
  
  CONCLUSIONS
  Although uncommon, mesentric fibromatosis must be considered in the differential diagnosis when evaluating a patient with an abdominal mass of unknown origin.
