Recurrent respiratory papillomatosis with pulmonary involvement: a case report and review of the literature.

Recurrent respiratory papillomatosis (RRP) is a viral infection that usually affects the upper airways. Although it can spread throughout the respiratory tract, involvement of the lung parenchyma is quite rare. Radiographic images of RRP with lung involvement have been mainly presented in case reports of paediatric patients. We present the case of an adult patient with RRP and lung involvement, and detail the serial radiographic manifestations. CT and reconstructed images were obtained. The literature was also reviewed and radiographic features of RRP with lung involvement are summarized.
