A Challenging Case of Malignant Struma Ovarii With Concurrent Papillary Thyroid Cancer
Bibliographic record
Abstract
Struma ovarii is a rare type of ovarian tumor that is predominantly composed of thyroid tissue. The majority of these are benign, with malignant struma ovarii (MSO) comprising only 5-10% of all cases. A 41-year-old female with a history of ovarian cystectomy for bilateral dermoid cysts presented with gallstone pancreatitis. Computed tomography (CT) scan revealed adnexal masses, peritoneal nodules, and a thyroid nodule. Surgery, including total hysterectomy and salpingo-oophorectomy, showed MSO and differentiated follicular carcinoma. Subsequent thyroidectomy revealed multifocal papillary thyroid carcinoma. Postoperative radioactive iodine therapy was given, and the patient has recovered fully. MSO may present as an ovarian mass, and the mainstay treatment is surgical resection. The rarity of this condition requires a multidisciplinary approach for optimal management. MSO should be considered in the differential diagnosis of ovarian masses. Early and accurate diagnosis, followed by appropriate surgical and adjuvant therapies, can lead to favorable outcomes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
