Thymoma Presenting as Right-Side Heart Failure in a Young Healthy Patient: A Case Report and Literature Review
Bibliographic record
Abstract
Thymoma is a rare tumor yet the most common neoplasm of the anterior mediastinum, accounting for 20-25% of all mediastinal tumors. Its incidence peaks in the fourth and fifth decades of life. Usually thymoma is diagnosed incidentally on chest imaging, or when investigating patients with myasthenia gravis, or with chest symptoms such as cough, chest pain, or dyspnea. We report here the case of a 31-year-old male patient with a swinging heart due to thymoma who presented with abdominal ascites and lower limbs edema, treated successfully with surgery and radiotherapy. This is, to our knowledge, the first case of thymoma to present this way with right-side heart failure like symptoms. J Med Cases. 2016;7(8):315-319 doi: http://dx.doi.org/10.14740/jmc2478e

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.
