CT Findings of Pneumonia After Lung Transplantation

Abstract

The manifestations revealed on CT of bacterial, viral, and fungal pneumonia after lung transplantation are similar, consisting of a combination of consolidation, ground-glass opacification, septal thickening, pleural effusion, or multiple nodules. Therefore, these findings cannot be used to suggest the infectious organisms in this patient population.

HRCT findings in the lungs of primary care patients with lower respiratory tract infection

“…The clinical significance of this entity deserves further attention. Nevertheless, the HRCT findings observed in these patients correlated well with those reported by Tanaka et al (15) and Collins et al (5) in established pneumonia caused by different agents, where air space consolidations, centrilobular and acinar shadows, ground‐glass attenuation, septal thickening and bronchovascular bundle thickening are frequent findings. Pleural effusion, which has been frequently present in the quoted materials, was found in only 1 of our patients – and this patient was the only one requiring hospital care – which obviously reflects the less severe clinical picture of the outpatients.…”

CT Findings of Varicella Pneumonia After Lung Transplantation

“…In keeping with this hypothesis, the findings in our patient show considerable overlap with those described in other forms of pneumonia occurring in lung transplant recipients. Collins et al [7] reviewed the CT findings of 45 episodes of pneumonia occurring in 35 lung transplant recipients. Pulmonary nodules, ground-glass attenuation, septal thickening, and pleural effusions were common findings in bacterial, fungal, and cytomegalovirus pneumonia.…”

Approach to Imaging Pulmonary Disease in the Immune Compromised Host

“…Bacterial pneumonias tend to have consolidation in almost all cases, with a high incidence of associated ground-glass opacities and frequent nodules. 95 Nodules or masses following transplantation suggest infection, including bacterial, fungal, or mycobacterial, but bronchogenic carcinoma and PTLD also must be considered in the later post-transplant period. Pulmonary nodules occur in approximately 10% to 12% of lung transplant patients, typically in the transplanted lung.…”
