Info
Focal lucencies (emphysematous spaces) located centrally within the secondary pulmonary lobule, most of them with a central or peripheral dot representing the central bronchovascular bundle; predominantly located in the upper zones of each lobe.
Case Discussion
Pulmonary emphysema is defined as the "abnormal permanent enlargement of the airspace distal to the terminal bronchioles accompanied by destruction of the alveolar wall and without obvious fibrosis". Centrilobular is by far the most common type encountered, and is a common finding in asymptomatic elderly patients.
