In brief
Retrospective study of 18 adolescent girls demonstrates that MRI accurately differentiates functional from neoplastic ovarian lesions (93% accuracy) and directly influences management decisions in 74% of cases. MRI findings guided appropriate observation versus surgical intervention and enabled ovary-sparing resection in the majority of neoplastic cases.
Written by the GCMD Library team from the article.
Background
The utility of magnetic resonance imaging (MRI) in the diagnosis and management of pediatric ovarian lesions has not been well defined.
Methods
A retrospective review of all girls who underwent MRI evaluation of ovarian masses during the period 2009–2015 was performed. The accuracy of MRI was evaluated by comparing results with surgical findings, pathology reports, and subsequent imaging. The influence of the MRI on the treatment plan was specifically explored.
Results
Eighteen girls, 12–17years of age, underwent 27 MRIs, subsequent to ultrasound identification of ovarian lesions. Of 9 neoplastic lesions diagnosed on MRI, 8 (89%) were confirmed by surgical and pathological findings. Of 18 functional lesions, 17 (94.4%) were confirmed pathologically or by resolution on subsequent imaging. Twenty MRI exams (74%) directly influenced the treatment plan, by leading to appropriate operative intervention in 9 and appropriate observation in 11. The extent of ovarian resection was guided by MRI findings in 8 of 9 (89%) neoplastic lesions. For characterizing lesions as neoplastic, the sensitivity, specificity, negative predictive value, positive predictive value, and accuracy of MRI were 89%, 94%, 94%, 89%, and 93% respectively.
Conclusions
MRI can differentiate functional from neoplastic pediatric ovarian masses, and guide ovarian resection in appropriate cases.
