Pulmonary hamartoma

Case contributed by Dr Balint Botz

Presentation

Oncological follow-up. Incidental finding.

Patient Data

Age: 60 years
Gender: Male
CT

An about 23 mm solid, inhomogeneous nodule is visible in the right segment 10 of the lung. It contains popcorn-like calcifications and areas of fat density, thus being virtually pathognomonic for a benign pulmonary hamartoma

Case Discussion

The heterogeneous density, popcorn-like calcifications (and stability on multiple follow-up exams) all favor a benign pulmonary hamartoma.
