There is a possibility of misdiagnosis of another type of tumor or malignancy on preoperative biopsy. Be careful about a “confluence of shadows” or overlap of normal vascular and skeletal structures that can mimic a nodule on a chest radiograph. Further analysis of variation in volumetry measurements by different software packages should be undertaken and methods developed for standardisation.
