Tuberculous Pericarditis Presenting as Cardiac Tamponade: Role of Echocardiography
Bibliographic record
Abstract
Tuberculous pericarditis, a rare but potentially lethal manifestation of tuberculosis, poses diagnostic and therapeutic challenges in clinical practice. Its nonspecific clinical presentation often mimics other conditions, leading to delayed or missed diagnoses. We report a 25-year-old male with no past medical history, who presented with nonspecific symptoms such as fatigue, weight loss, body aches, and dyspnea. An electrocardiogram showed low voltage QRS complex with electrical alternans, and transthoracic echocardiography (TTE) showed large pericardial effusion with tamponade physiology with right ventricular diastolic collapse, the collapse of the right atrium and the inferior vena cava was dilated with a respiratory variation of less than 50%. The diagnosis of tuberculous pericarditis was made based on clinical presentation, imaging, and laboratory findings, including a positive QuantiFERON-TB gold test and pericardial fluid analysis, despite negative cultures. This case highlights the significance of considering tuberculosis in the differential diagnosis of pericardial effusion and underscores the role of imaging and laboratory investigations in diagnosis. Management of tuberculous pericarditis involves a combination of antituberculous chemotherapy, pericardiocentesis, and corticosteroids. Despite its rarity, tuberculous pericarditis carries a high mortality rate and can present as cardiac tamponade, as illustrated in our case. This underscores the need for high clinical suspicion, especially in high-risk populations, for timely diagnosis and initiation of treatment.

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.
