A retrospective case series at a tertiary hospital in china: ultrasonographic features of Struma ovarii

Ultrasonographic features-including multilocular cystic-solid masses with septations, hyperechoic "pearl signs," and comet-tail artifacts-may raise suspicion for SO. However, differentiating between benign and malignant cases remains challenging due to significant imaging overlap. A multimodal diagnostic approach incorporating clinical presentation, laboratory findings, and histopathological evaluation is essential for accurate diagnosis and optimal management.
