CTICasesMucinous Adenocarcinoma
Imaging findings
Chest CT shows synchronous lung tumors, with a large mass in the left apex and a smaller nodule in the right upper lobe. The left apical mass contains large, amorphous, flocculent calcifications and speculates/invades the pleural surface and chest wall.
Key takeaways
Primary lung adenocarcinomas, particularly mucinous subtypes, can present with prominent amorphous or flocculent calcifications. They can be synchronous with other lung primary cancers. Calcification in a mass does not always indicate benignity.
