Learning objectives
To illustrate and correlate key radiological and imaging findings which may provide a correct diagnosis.
To compare US, MRI and contrast-enhanced CT agreement in characterizing ovarian masses.
To identify thespecific features of tumors in each imaging modality.
Background
Ovariantumors in pediatric population are uncommon compared to adult females, but not rare, only with a different incidence profile. Most tumors found under the age of 18 years are benign, with origin from germ cell line.
Tumors of the ovary can be placed into one of three major categories(Fig. 1) —according to the anatomic structures from which the tumors presumably originate:
surface epithelial-stromal tumors;
sex cord-stromal tumors;
germ cell tumors.
Ovarian tumors have similar clinical and imaging features, but specific keycharacteristicsmay be present in some...
Findings and procedure details
Imaging investigation methods
Characterization of ovarian lesions is of great importance in order to plan adequate therapeutic procedures. Optimal assessment of adnexal masses requires a multidisciplinary approach, based on physical examination, laboratory tests and imaging techniques.
1. Ultrasound (US)is often the first imaging study performed in the evaluation of a suspected ovarian lesion because it’s widely available, well accepted by patients, non-invasive and of low cost.
2. Computed Tomography (CT)is the imaging technique of choice instagingand therapy response evaluation.
3. Magnetic Resonance Imaging (MRI)is an...
Conclusion
US, CT and MR imaging all have a similar accuracy in detecting morphological characteristics of adnexal masses with extracredit for CT scanin assessing the disease extent and MR imaging for providing specific information in accurately diagnosing anovarian mass.
