Pheochromocytoma in a Pregnant Woman With Prior Traumatic Aortic Injury
Bibliographic record
Abstract
In Brief BACKGROUND: Pheochromocytoma, a catecholamine-producing tumor seldom encountered in pregnancy, is often heralded by nonspecific symptoms and undue mortality with delayed diagnosis. The presence of an aortic pseudoaneurysm poses a management challenge given the risk of aortic rupture amplified by hypertensive events. CASE: A 30-year-old woman, gravida 3 para 1, presented at 23 6/7 weeks of gestation with vomiting, chest pain, and severe hypertension. Investigation revealed adrenal pheochromocytoma and pseudoaneurysm at the site of a previous aortic injury. Prazosin and phenoxybenzamine achieved α-blockade with subsequent addition of labetalol for β-blockade. Concerns for aortic dissection led to endovascular aortic repair at 30 2/7 weeks of gestation. A female neonate was delivered by urgent cesarean delivery for persistent postprocedure fetal bradycardia. An adrenalectomy followed with near-immediate symptom resolution. Mother and neonate remain well. CONCLUSION: The case underscores the necessity of a meticulous approach to hypertension management and the pivotal role of diligent multidisciplinary collaboration to achieve a safe outcome. Pheochromocytoma, a catecholamine-producing tumor seldom encountered in pregnancy, requires a high index of suspicion, specific management approach, and multidisciplinary involvement to achieve positive pregnancy outcomes.

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.
