Partial biochemical response of adrenal artery embolization for pheochromocytoma: A case report and review of the literature
Bibliographic record
Abstract
We present the case of a 22-year-old male with a left adrenal pheochromocytoma, initially diagnosed during a workup for thoracic pain. The patient's tumor was refractory to medical management, and surgical resection was ruled out due to high cardiovascular risk, stemming from cyanotic congenital heart disease, aortic aneurysm, and factor VII deficiency. The patient underwent adrenal artery embolization (AAE) as a salvage treatment. Following the procedure, there was an initial reduction in hypertensive crises and biochemical markers, with plasma normetanephrine levels decreasing from 1490 pg/mL to 313 pg/mL. However, over subsequent months, the patient experienced symptom recurrence, and biochemical relapse occurred, with normetanephrine levels rising to 742 pg/mL by 3 months postprocedure. This case highlights the potential for AAE to provide short-term symptom relief and biochemical response; nevertheless, it may not be an effective long-term curative option. More collaborative and prospective studies are needed to assess its success and efficacy.

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.
