title: Brenner tumors of the ovary: sonographic and computed tomographic imaging features.
abstract: OBJECTIVE
  The purpose of this study was to describe the sonographic appearance of ovarian Brenner tumors with computed tomographic (CT) correlation.
  
  
  METHODS
  Twenty-two female patients (age range, 32-78 years; mean, 58 years) with 25 ovarian Brenner tumors were identified from pathologic records from 1990 to 2005. Corresponding pathologic reports and images (17 sonographic and 14 CT) were reviewed independently.
  
  
  RESULTS
  Tumors ranged in size from 0.3 to 12 cm (mean, 2.5 cm); all were benign. Sixteen (64%) of 25 were found incidentally. Eight (36%) of 22 patients had a total of 12 associated benign ovarian neoplasms (1 was contralateral); 3 patients had bilateral Brenner tumors. Eight (47%) of 17 tumors were not seen on sonography, and 5 (36%) of 14 were not seen on CT. Of the tumors seen on imaging, most were solid (67% on sonography and 78% on CT). Four tumors appeared at least partially cystic, of which 3 had coexistent cystic ovarian lesions.
  
  
  CONCLUSIONS
  Brenner tumors are most often solid neoplasms found incidentally and frequently seen in association with other benign ovarian epithelial neoplasms.
