CT–Pathology Comparisons

Because of the pathogenetic association with pleural Þbrosis, RA usually occurs in the peripheral lung adjacent to the visceral pleura. Pathologic examination shows pleural Þbrosis overlying the abnormal lung parenchyma as well as invaginations of Þbrotic pleura into the region of collapse. The appearance suggests that retraction of collagen in the pleura as it matures is the cause of the collapse [8].

Patient Prognosis

RA usually remains stable over time; however, slow growth as well as diminution in size has been described [9].
