A few potential organisms come to mind, including:

  • Candida albicans

  • Coxsackievirus B

  • Group A streptococcus

  • Mycobacterium tuberculosis

  • Staphylococcus aureus

The water bottle sign in this patient suggests a large pericardial effusion. 

The radiographic findings in patients with candidiasis/candidemia and group A streptococcus are non-specific. In contrast, findings in patients with Coxsackievirus B infections generally include consolidation, nodularity, and effusions.

The radiographic findings in patients with Staphylococcus aureus include consolidation and interstitial lung disease.

While pericardial effusions most often have a viral etiology, hemorrhagic pericarditis is most often associated with tuberculosis or a malignancy. M. tuberculosis is the most likely culprit organism in this patient.
