Hungry bone syndrome and bone scintigraphy in a post parathyroidectomy patient
Bibliographic record
Abstract
1058 Learning Objectives 1. Understand the pathophysiology of hungry bone syndrome. 2. Illustrate the appearance of hungry bone syndrome on bone scintigraphy. 3. Discuss the biochemical changes in hungry bone syndrome. A 42-year-old man with a history of multiple renal stones presented with right leg pain. Plain radiographs showed a lytic lesion at the proximal tibia. Bone scintigraphy demonstrated a metabolic superscan with mildly increased uptake at the tibial lesion. Sestamibi scanning showed evidence of a large parathyroid adenoma. Following parathyroidectomy, the patient experienced hypocalcemia and worsening of his leg pain. Repeat bone scintigraphy showed an increase in the intensity of uptake at the tibial lesion and the appearance of new lesions in keeping with brown tumors. This flare-up phenomenon is consistent with hungry bone syndrome which occurs after an abrupt decrease in parathyroid hormone following parathyroidectomy

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.
