Musculoskeletal Point-of-Care Ultrasound for the Detection of Active Haemorrhage in Intramuscular Haematoma: A Case Report
Bibliographic record
Abstract
A 73-year-old man on chronic warfarin therapy presented to the emergency department with acute right thigh pain and swelling, without a history of trauma. Musculoskeletal point-of-care ultrasound (MSK-POCUS) rapidly identified an intramuscular hematoma with evidence of active hemorrhage. Subsequent computed tomography angiography (CTA) confirmed a sizable hematoma in the right vastus intermedius muscle and detected a small pseudoaneurysm. The patient was managed conservatively, with close monitoring yielding no further complications. This case demonstrates the diagnostic utility and efficiency of MSK-POCUS in the acute evaluation of musculoskeletal complaints, particularly in patients at risk for anticoagulant-induced bleeding. The report highlights the value of bedside ultrasound for prompt diagnosis, its advantages over other imaging modalities in emergency settings, and the importance of enhancing training for widespread POCUS implementation in clinical practice.

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.
