A Solid Pseudopapillary Tumor Arising in Ovary With Multiple Metastasis: A Case Report

Solid pseudopapillary tumors (SPTs) are rare low-grade malignant epithelial tumors that primarily originate in the pancreas. They can also occur in extrapancreatic areas, such as the ovaries; however, these cases are extremely rare. Here, we report a case of primary ovarian SPT with extensive metastasis detected on ultrasonography, computed tomography, and magnetic resonance imaging. This report presents a case of SPTs in a 31-year-old woman with right lower outer quadrant pain. Owing to their rarity and diverse imaging features, accurate diagnosis of ovarian SPTs based solely on imaging is challenging. Therefore, careful evaluation is essential for proper diagnosis and treatment. Moreover, a comprehensive understanding of SPT originating in the ovary will benefit clinicians, radiologists, and pathologists in the differential diagnosis of suspected oval pelvic cavity masses.
