Haemangiosarcoma of the interventricular septum in a dog
Bibliographic record
Abstract
UNLABELLED: Abstract CASE HISTORY: A 5-year-old male neutered Labrador Retriever Afghan crossbred dog was examined after collapsing. The dog was recumbent, dyspnoeic and mildly tachypnoeic. There was a tachyarrhythmia (300 beats per minute) and subcutaneous oedema of the ventral neck and right forelimb. CLINICAL FINDINGS: The dog had a sustained ventricular tachycardia originating in the right ventricle and on echocardiography a mass was identified in the interventricular septum. Due to the poor prognosis the owners agreed to euthanasia of the dog. PATHOLOGICAL FINDINGS: A reddish-grey mass was found in the interventricular septum and smaller red foci found scattered throughout the myocardium. There was a single, raised, splenic nodule with several smaller red foci within the splenic parenchyma. Hepatic congestion, pancreatic oedema, ascites and subcutaneous oedema of the right forelimb and neck were present. Sections of the splenic nodule, interventricular septal mass and both ventricular-free walls showed neoplastic mesenchymal cells. DIAGNOSIS: Haemangiosarcoma of the myocardium and spleen with right-sided congestive heart failure. CLINICAL RELEVANCE: This case report describes an atypical location for haemangiosarcoma. The investigation supports the use of echocardiography as a component of the protocol for staging haemangiosarcoma even in the absence of apericardial effusion. It also provides further evidence for the inclusion of intracardiac neoplasia as a differential diagnosis for dogs with unexplained cardiac arrhythmias.

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.
