504 　Bilateral ureteral compression by multiple abdominal desmoid tumors in Gardner’s syndrome has been described [9]. That case was managed by placement of a percutaneous nephrostomy tube and surgical removal of the desmoid tumors. Ng et al reported another case of hydronephrosis in mesenteric fibromatosis with Gardner’s syndrome that was treated successfully with a cyclooxygenase-2 inhibitor [10]. In our case, the patient was treated by surgical ex- cision of the mass, and she has been free of the tumor for 2 months. 　MF and MF-induced ureteral stenosis is very rare. Although many mesenteric fibromatoses can be un- resectable, patients with MF can undergo treatment suc- cessfully if we have an appropriate management plan in- cluding surgery and medical therapy.
