Given the patients history of cancer, recurrence was high on the differential and needed to be thoroughly evaluated. Nodular disease can also be found clustered around the fissures, along the interlobular septae, and along the pleura. Several numerical systems have been proposed for identifying the specific locations of intrathoracic lymph nodes (i.e., lymph node stations ), primarily for the purpose of lung cancer staging. Lymph node calcification usually indicates prior granulomatous disease, including tuberculosis, histoplasmosis and other fungal infections, and sarcoidosis ( Fig. Lung Cancer Stage Based on TNM classification (Eighth Edition, 2017), Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), on Mediastinum: Lymph Node Abnormalities and Masses, Introduction to CT of the Thorax: Chest CT Techniques, Mediastinum: Introduction and Normal Anatomy, Carcinoma in situ: adenocarcinoma in situ or squamous cell carcinoma in situ.
