Suspected olfactory meningioma and synchronous pituitary microadenoma in a canine patient treated with radiation therapy
Bibliographic record
Abstract
Abstract The authors report on the rare occurrence of dual synchronous primary brain tumors in a canine patient, successful treatment with radiation therapy, and medical therapy with patient stabilization for almost three years. A 12.5-year-old spayed mixed-breed female Labrador was referred to Purdue Veterinary Hospital to treat hyperadrenocorticism of suspected pituitary origin. During MRI imaging, the presence of two possible brain neoplasms was detected: a possible right olfactory bulb meningioma and a microadenoma of the pituitary gland. The patient was treated with a fractionated course of radiation in both tumors, 15 treatments of 3Gy, which limited the tumor growth. Mitotane therapy corrected the hormonal dysregulation. The dog had a normal life for nearly three years and recently passed. Cancer cells were not found at necropsy. No MEN1 germline mutations were identified in constitutional DNA (from blood) via high-coverage whole genome sequencing.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
