Summary
Struma ovarii, a rare ovarian teratoma, can metastasize to the peritoneum. This case highlights the diagnostic utility of 99mTcO4 whole-body scintigraphy SPECT/CT in identifying recurrent struma ovarii with extensive peritoneal implants.
Area of Science:
- Reproductive medicine
- Endocrinology
- Oncology
Background:
- Struma ovarii is a rare ovarian germ cell tumor, predominantly consisting of mature thyroid tissue.
- Recurrence and metastasis of struma ovarii, though uncommon, can occur, presenting diagnostic challenges.
- This case involves a 55-year-old woman with a history of struma ovarii resection presenting with recurrent disease.
