Summary
This study reports three cases of struma ovarii diagnosed via histopathology. Low resistive index (RI) and pulsatility index (PI) were observed in two cases, suggesting potential diagnostic markers for this rare ovarian tumor.
Area of Science:
- Gynecologic Pathology
- Endocrinology
- Reproductive Medicine
Background:
- Struma ovarii is a rare germ cell tumor of the ovary containing thyroid tissue.
- Diagnosis often relies on postoperative histopathological examination.
- Clinical presentation can vary, including asymptomatic findings, abdominal pain, or symptoms of hyperthyroidism.
Observation:
- Presents three cases of struma ovarii diagnosed between 1994-1997.
- Case 1: Incidental finding in a menopausal woman.
- Case 2: 39-year-old woman with hyperthyroidism and struma parenchymatosa-nodosa.
- Case 3: 21-year-old woman presenting with abdominal pain.
Findings:
- Postoperative histopathological examination confirmed struma ovarii in all three cases.
- Doppler flowmetry in the first two cases showed low resistive index (RI < 0.5) and pulsatility index (PI < 0.7) within the tumor.
- These low vascular indices may indicate specific characteristics of struma ovarii.
Implications:
- Highlights the importance of histopathological diagnosis for struma ovarii.
- Suggests that low RI and PI values in Doppler flowmetry could be potential indicators for struma ovarii.
- Contributes to understanding the varied clinical presentations and diagnostic possibilities of this ovarian neoplasm.
