Imaging findings
A very well-defined nodule located adjacent to the left pulmonary artery, which remained stable over two years on radiographs. CT demonstrated a central lesion containing intralesional calcifications and some low-density areas. Pixel mapping did not reveal microscopic fat.
Key takeaways
This case features a rare lesion, sclerosing pneumocytoma (historically known as sclerosing hemangioma), characterized by its stability over time and internal calcifications. It is more commonly reported in Asian females. The histological appearance often includes dilated vascular spaces, making it histologically similar to a hemangioma.
