ABSTRACT
Isolated native non‑rheumatic tricuspid valve infective endocarditis (TVIE) is rarely diagnosed in the absence of intravenous drug use, intracardiac catheters, or cardiac anomalies. Staphylococcus aureus is the most common organism causing TVIE. Most patients
with TVIE are successfully treated with antibiotics; however, 5–16% of TVIE cases eventually require surgical intervention.
We report a case of a 25‑year‑old female patient who presented with fever and respiratory symptoms. She was initially suspected of tuberculosis based on her symptoms and X‑ray features but later was found to have TVIE on 2-Dimensional Echocardiography(2D‑ECHO). She was treated successfully with antibiotics susceptible to S. aureus for 6 weeks. This case report shows that TVIE due to S. aureus can masquerade as tuberculosis, and awareness of this entity during treatment is crucial.
