A rare ‘incidentaloma’ found on low-dose CT screening for lung cancer: ‘scanner beware’

ABSTRACT

Screening for lung cancer with low-dose computed tomography (LDCT) has been shown to reduce mortality and has been recommended by the U.S. Preventive Services Task Force for adults 55 to 80 years of age with a 30 pack-year smoking history who are either current smokers or those that quit within 15 years. However, the overwhelming majority of abnormalities detected are not from malignancy. We report a case of pulmonary Langerhans’ cell histiocytosis, here-to-fore thought of as extremely uncommon, and make readers aware that this may be increasingly found as LDCT is more widely adopted.
