Importance of Ultrasound Imaging in Pheochromocytoma in a Child: Case Report and Review of Literature
Bibliographic record
Abstract
Pheochromocytomas are rare tumors, originating from adrenal medulla (80-90%), diagnosed at 0.1% of cases with hypertension. Not very rare (40%), diagnosis can be insidious during ultrasound imaging (US) for a non-specific complaint. We are presenting a 13 years old boy who had suffered from non-specific headache without hypertension and any of autonomic disorders, diagnosed by increased urine catecholamine after a mass seen in US. A 13 years old boy has admitted to emergency with blood pressure measurement of 160/110 mmHg. He had severe headache for 18 months without hypertension. In physical exam, hypertension, tachycardia, tremor, and Marfanoid morphology were found. Ultrasound revealed an incidental mass of 33 ? 68 mm, with increased vascularization, on pre- and para-aortic sides. Urinary catecholamine and metabolites were grossly elevated. Iodine-131-metaiodobenzylguanidine scintigraphy also showed the heterogeneous mass located in the right para-aortic region, neighboring the liver. Pheochromocytoma is a rare catecholamine-producing tumor, and has life-threatening consequences. Clinical manifestations can be non-specific. It can be easily diagnosed if it is suspected or screened by US. Here we want to emphasize that such an easy and cheap method (screening by US) can lead us to know earlier this high complicated and incidental disease.

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.
