Radiologic findings: pulmonary infections after bone marrow transplantation

Area of Science:

• Medical Imaging
• Infectious Diseases
• Hematology

Background:

• Bone marrow transplantation (BMT) is a critical treatment for various hematologic malignancies and other diseases.
• BMT recipients are highly susceptible to pulmonary infections due to profound immunosuppression.
• Pulmonary infections are a leading cause of morbidity and mortality in the BMT population.

Purpose of the Study:

• To review the common pulmonary pathogens encountered in bone marrow transplant recipients.
• To correlate the typical timing of infection post-transplant with specific pathogens.
• To illustrate characteristic imaging findings for early diagnosis and management.

Main Methods:

• This is a pictorial essay, relying on review of imaging studies.
• Case examples of common pulmonary infections in BMT patients are presented.
• Radiological findings are correlated with microbiological data and clinical context.

Main Results:

• Specific pathogens have characteristic temporal patterns of occurrence post-BMT.
• Imaging findings such as consolidation, ground-glass opacities, and nodules are associated with particular infections.
• Early recognition of imaging patterns aids in prompt etiological diagnosis.

Conclusions:

• Familiarity with the spectrum of pulmonary infections and their imaging manifestations is crucial for BMT clinicians and radiologists.
• Timely and accurate diagnosis based on imaging can significantly impact patient outcomes.
• Integrated clinical and radiological assessment improves the management of pulmonary complications in BMT.
