CTICasesCalcified Carcinoid Tumor
Imaging findings
A 32-year-old nonsmoker had a large lung nodule on chest radiograph and outside CT with a distal obstructive phenomenon, showing an amorphous, cloud-like pattern of calcification rather than central or stippled calcification. PET showed minimal metabolic activity within the mass, and the lesion proved to be a typical carcinoid tumor.
Key takeaways
Amorphous, cloud-like calcification within a large, low-metabolic-activity pulmonary nodule in a young nonsmoker is a distinctive and comparatively rare but well-recognized appearance of a calcified carcinoid tumor, distinct from the more common central or popcorn-type calcification patterns seen with other benign or malignant lung nodules.
