title: Comparison of underlying lesions in pediatric and adult ovarian torsion.
abstract: OBJECTIVE
  To compare the pediatric and adult ovarian torsion and explore a quantitative value to predict a possible underlying tumor.
  
  
  METHODS
  This study included 32 pediatric and 33 adult female cases diagnosed with ovarian torsion and underwent surgical treatment in Dr. Behcet Uz Children's Research Hospital and Ataturk Education and Research Hospital, Izmir, Turkey between 1989 and 2005. We evaluated the properties of the cases statistically.
  
  
  RESULTS
  The mean age of pediatric was 8 years and 3 months and adult cases was 39 years and 8 months. Six cases had an underlying tumor in both pediatric and adult group. The mean diameter and volume difference were 6.84 cm, 91 cc in pediatric and 12.69 cm and 1087 cc in the adult group. In statistical analysis, the diameter and volume increase were significantly higher in cases with underlying tumor in pediatric group. The cut-off value was 7 cm in diameter and 104 cc in volume increase. In the adult group, the diameter and volume increase were not significant in tumor positive and negative group.
  
  
  CONCLUSIONS
  Torsion of the ovary requiring surgery, is rare and is the mot common reason of abdominal/pelvic mass. These cases are often difficult to decide for surgical procedure especially in pediatric cases. We conclude that an underlying lesion more commonly occurs in children with an increase in ovarian volume of more than 104 cc and a diameter more than 7 cm. Great care should be taken for laparoscopic conservative management especially in these cases. The quantitative analysis is not predictive for the underlying solid lesion in adult cases.
