Struma ovarii—diagnostic and treatment strategy: a case report
Struma ovarii is an uncommon ovarian tumor primarily composed of thyroid tissue, accounting for approximately 1-3% of ovarian teratomas. We present the case of a 68-year-old Chinese female patient presenting with recurrent urethral outlet tumescence and an adnexal mass, whose diagnosis was established through ultrasonography, pelvic computed tomography, and magnetic resonance imaging. Subsequently, the patient underwent laparoscopic left adnexectomy, and histopathological examination confirmed the presence of struma ovarii in the left ovary. Struma ovarii poses unique diagnostic and management challenges owing to its rarity. A multidisciplinary approach incorporating clinical, imaging, and histological evaluations is essential for accurate diagnosis and optimal treatment outcomes. Surgical excision remains the cornerstone of treatment, typically resulting in a favorable prognosis when performed promptly and appropriately.
