Presentation
Restrictive lung function, increased shortness of breath, finger clubbing. Query interstitial lung disease or bronchiectasis.
Patient Data
3.4 cm rounded calcified nodule within the left upper zone.
Imaging features in keeping with a benign hamartoma.
No evidence of bronchiectasis or ILD noted.
Minor dependent atelectasis, lungs otherwise clear with no acute abnormality noted.
The heart and mediastinum appear normal.
No mediastinal lymphadenopathy noted.
No major collapse, consolidation or pleural effusion noted.
Note is made of the minor thickening of the Rt lung minor fissure.
Incidentally, a sharply demarcated, lobulated lesion is noted in the left lung upper lobe containing coarse, irregular calcification suggestive of a benign hamartoma.
Case Discussion
Hamartomas are benign lesions and can be found in multiple organs.
Interval chest x-rays in this case show no interval growth or change.
Most lesions are less than 3cm in diameter, but can be up to 10cm.
As in this case, the margins are well defined and sharp, with an internal matrix of ‘popcorn’ calcification.
