Presentation
Fever, cough and severe dyspnea. Thoracic CT was performed on the day of the admission. Rapid deterioration of her respiratory status necessitated intubation the next day. She remained on assisted ventilation for nearly three weeks, before improving again. The patient was discharged 6 weeks after admission.
Patient Data
Scattered centrilobular opacities in a tree-in-bud pattern throughout both lungs. One relatively small subpleural consolidation area is noted posterior-inferiorly on the left. No other consolidation or atelectasis. No ground-glass opacities. No pleural effusion. Prominent mediastinal lymphadenopathy.
Case Discussion
Bronchoscopy was performed and microbiologic assessment demonstrated pulmonary Haemophilus influenzae infection. This case of Haemophilus pneumonia is rather typical in its presentation. In many cases, there is a degree of discrepancy between the often subtle imaging findings and the clinical severity, with many of these patients requiring assisted ventilation. There is relatively high mortality, especially in the elderly.
