CTICasesRhinovirus Pneumonia in a Lung Transplant Recipient
Imaging findings
Sequential CTs in a bilateral lung transplant patient demonstrate new patchy bilateral ground-glass opacities over a period of a few days, with dilated vessels in the consolidative areas. The pattern is non-specific and indistinguishable from COVID-19 or other viral pneumonias on imaging alone. BAL confirmed rhinovirus.
Key takeaways
Rhinovirus (common cold virus) is an underrecognized cause of severe viral pneumonia in immunocompromised hosts, particularly lung transplant recipients. CT findings are non-specific and overlap with other viral pneumonias including COVID-19. Clinical differentiation requires molecular testing (PCR) of respiratory secretions or BAL. In the transplant population, rhinovirus pneumonia can precipitate acute rejection.
