Benign diagnoses include granulomas, hamartomas, organizing pneumonia, abscess or fungal infections, tuberculosis, chondromas
, Wegener granulomatoses, arteriovenous malformations, sarcoidoses, hematomas, rounded atelectases, and bronchopulmonary sequestration.
Of these patients, there were 13 cases of giant cell tumor, three periosteal chondromas
, as well as three other benign diagnoses.
