Presentation
Cough and shortness of breath.
Patient Data







The left lung contains a well-defined 32 mm mass with internal coarse calcification and tiny areas of fat density, typical for hamartoma.
Also, a few small calcified nodules, less than 7 mm, are scattered throughout both lung fields.
Case Discussion
Pulmonary hamartomas are benign neoplasms of cartilage, connective tissue, muscle, fat, and bone. The presence of fat and coarse popcorn-like calcification in a well-circumscribed solitary pulmonary nodule that does not demonstrate significant growth is essentially pathognomonic of a pulmonary hamartoma, and no further investigations are required.
