CTICasesLymphangitic carcinomatosis from thyroid cancer
Imaging findings
Chest CT demonstrates radiation fibrosis at the lung apices and classic, nodular, beaded thickening of the interlobular septa from thyroid cancer, which progressively worsened over time.
Key takeaways
Lymphangitic carcinomatosis manifests radiographically as nodular, beaded septal thickening due to tumor infiltration of the pulmonary lymphatics. It can arise from thyroid cancer and presents as progressive interstitial thickening.
