Prenatal Diagnosis of a Mass in the Adrenal Region That Proved to be a Teratoma
Bibliographic record
Abstract
A prenatally detected suprarenal cystic mass measuring 2 cm was found to have enlarged upon postnatal ultrasonography at 6 weeks of age. Magnetic resonance imaging showed a 57 x 50 mm mass in the left adrenal region displacing the kidney inferiorly. The infant underwent an adrenalectomy with total resection of the tumor, which proved on histologic examination to be a mature teratoma. Prenatally detected suprarenal masses are likely to be neuroblastoma or adrenal hemorrhage, but may be rare benign lesions such as extralobar pulmonary sequestration, bronchogenic cyst, or renal dysplasia. Although teratoma in the adrenal region is extremely rare, it should be included in the clinical and radiologic differential diagnosis of prenatally detected suprarenal masses. Total excision of the mass for histologic diagnosis is indicated.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
