Eggshell Calcification Mediastinal Lymphadenopathy

Eggshell Calcification Definition:

• Mediastinal lymphadenopathy where the periphery of the nodes are calcified - eggshell calcification.
• Sometimes the central portions may also show calcification.
• The ringlike shadow must be complete in at least one of the lymph nodes to fulfil the radiological criteria.

Important Causes:

• Coal worker's pneumoconiosis
• Lymphoma
• Sarcoidosis
• Silicosis

Other rare causes:

• Amyloidosis
• Blastomycosis
• Histoplasmosis
• Scleroderma
• Tuberculosis

Honeycomb Lung Causes

Honeycomb Lung Causes (A-Z):

• Acute interstitial pneumonitis survivors
• Allergic alveolitis
• Bronchiectasis (cystic fibrosis)
• Collagen diseases (rheumatoid disease, scleroderma)
• Drug-induced (bleomycin, cyclophosphamide, nitrofurantoin)
• Eosinophilic granuloma
• Neurofibromatosis
• Non-specific interstitial pneumonitis (uncommonly)
• Pneumoconiosis (asbestosis)
• Sarcoidosis
• Usual interstitial pneumonitis
