Hypertension and a Large pulsatile neck mass: A Case of Malignant Glomus Vagale Tumour
Bibliographic record
Abstract
This teaching case report represents an unusual example of a neck mass in a previously healthy individual. The presence of a new neck mass is a relatively common head and neck problem and requires a full work up including a complete history and physical examination. With respect to our patient, thorough history taking, physical examinations and specific investigations led to the diagnosis of a malignant and functionally active paraganglioma. Vagal paraganglioma themselves are rare tumours and account for only 5-25% of all paragangliomas in the head and neck region. The presence of a malignant, functionally active, catecholamine-secreting paraganglioma is even rarer and accounts for only 1-3% of all reported glomus vagale tumours. This case report illustrates the need to carefully monitor all neck masses for changes in size, for any distortion to surrounding structures, and their given function.
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.
