CTICasesCalcifying Metastases from Colonic Adenocarcinoma
Imaging findings
A smoker with colonic adenocarcinoma developed a lobulated, irregular lung metastasis with cystic change; over serial follow-up studies spanning about two years of treatment, liver metastases and lung metastases progressively calcify, and previously non-calcified mediastinal lymph nodes containing tumor, including a prevascular node, develop increasing calcium content as the metastases slowly grow.
Key takeaways
Calcification developing within growing metastatic deposits and involved lymph nodes, rather than representing granulomatous disease, is a recognized phenomenon in several GI and GU malignancies, particularly mucinous colorectal and ovarian cancers, and can reflect either a tumor-intrinsic calcifying process or a treatment effect; awareness of this pattern prevents mistakenly attributing calcified adenopathy in a cancer patient to old granulomatous disease when it may in fact represent calcified tumor.
