Materials and Methods
Our institutional review board approved our retrospective study with a waiver of informed consent.
Demographic Findings
Three patients had associated conditions, as follows: two patients, Sjögren syndrome; one patient, systemic lupus erythematosus. Four men were smokers (mean smoking history, 27 pack-years; range, 20 to 35 pack-years), and the remaining 17 men were nonsmokers. Nine patients had respiratory symptoms (cough, seven patients; dyspnea, four patients). In 12 asymptomatic patients, lung abnormalities were detected incidentally. For these patients, a chest CT scan was performed for the following other
Discussion
According to a study7 describing 10 cases of marginal zone B-cell lymphoma of BALT, the main patterns of lung lesions seen on CT scans were airspace consolidation or nodules containing air bronchograms within the lesions. In this study, the lesions were multiple in seven cases (70%) and bilateral in six cases (60%). In our study, a multiplicity of lesions was observed in 14 patients (70%), and bilateral disease was observed in 9 patients (43%). Moreover, in our study, CT scan findings were more
