Summary

Wegener granulomatosis can rarely present as culture-negative endocarditis with aortic valvular vegetation. Early diagnosis and treatment with corticosteroids and cyclophosphamide are crucial for managing this rare vasculitis presentation.

Area of Science:

  • Rheumatology
  • Cardiology
  • Infectious Diseases

Background:

  • Cardiac involvement in Wegener granulomatosis (WG) is infrequent.
  • Distinguishing WG from bacterial endocarditis can be challenging due to overlapping clinical features.

Observation:

  • A case of WG presented with culture-negative endocarditis and aortic valvular vegetation.
  • Clinical manifestations included gingival hyperplasia, digital infarcts, mononeuritis multiplex, fever, arthritis, and pansinusitis.

Findings:

  • Valvular vegetation, typically associated with bacterial endocarditis, was observed in a patient with WG.
  • This case challenges the conventional understanding of valvular vegetation as solely indicative of bacterial infection.

Implications:

  • Highlights the importance of considering systemic vasculitis in cases of culture-negative endocarditis.
  • Emphasizes early corticosteroid and cyclophosphamide treatment to prevent severe complications in WG with cardiac involvement.
