Abstract:
Pasteurella multocida has been implicated as the cause of a variety of respiratory conditions (eg, bronchitis, pneumonia, lung abscess, empyema), but hemoptysis has been noted only in conjunction with other lung conditions. We report a case in which hemoptysis was the sole manifestation of Pasteurella infection. The patient was a middle-aged man with severe obstructive lung disease and exposure to cats. Diagnosis was made by bronchoscopy and high-dose penicillin was required for resolution.
Insights
Pasteurella multocida typically causes lung issues, but this case showed hemoptysis as the only symptom. Prompt diagnosis and high-dose penicillin resolved the infection in a patient with severe obstructive lung disease.
Area of Science:
- Infectious Diseases
- Pulmonology
- Microbiology
Background:
- Pasteurella multocida is a known pathogen causing diverse respiratory infections, including pneumonia and bronchitis.
- Hemoptysis (coughing up blood) is an uncommon presentation, usually associated with concurrent lung pathologies.
Observation:
- A middle-aged male patient with severe obstructive lung disease presented with hemoptysis as the sole clinical manifestation.
- The patient had a history of exposure to domestic cats, a common reservoir for Pasteurella multocida.
Findings:
- Bronchoscopy confirmed Pasteurella multocida infection presenting solely as hemoptysis.
- Treatment with high-dose penicillin was effective in resolving the infection and symptoms.
Implications:
- This case highlights that hemoptysis can be the exclusive sign of Pasteurella multocida infection, even in immunocompromised individuals.
- Clinicians should consider Pasteurella multocida in the differential diagnosis of hemoptysis, particularly in patients with risk factors like COPD and animal exposure.
- Early diagnosis via bronchoscopy and appropriate antibiotic therapy are crucial for favorable outcomes.
