Calcified pulmonary nodules are a subset of hyperdense pulmonary nodules and a group of nodules with a relatively narrow differential.

Pathology

Etiology

The most common cause of nodule calcification is granuloma formation, usually in the response to healed infection.

healed infection
- calcified granulomata, e.g. thoracic histoplasmosis, recovered miliary tuberculosis (rare)
  - most common
  - 2-5 mm
  - calcification may be central or diffuse
  - usually with calcification of hilar/mediastinal nodes
- healed varicella pneumonia
  - micronodular (1-3 mm)
  - no associated nodal calcification
occupational disease/pneumoconioses
- silicosis
  - associated with nodal egg-shell calcification
  - multiple small densely calcified nodules in mid and upper zones
- coalworker's pneumoconiosis
  - smaller nodules which may not be visible on plain film
  - associated with minimal symptoms
pulmonary hamartomas
metastatic pulmonary calcification
- typically nodules are poorly defined and larger (3-10 mm)
- calcium and phosphate metabolism abnormalities
  - chronic renal failure
  - multiple myeloma
  - secondary hyperparathyroidism
  - massive osteolysis caused by metastases
  - intravenous calcium therapy
pulmonary hemosiderosis
- idiopathic pulmonary hemosiderosis
  - recurrent alveolar hemorrhage
  - centrilobular nodular opacities
- mitral stenosis
  - small multifocal calcified nodules
- Goodpasture syndrome
pulmonary alveolar microlithiasis
- tiny micronodules
- apparent calcification of interlobular septa
- small subpleural cysts
sarcoidosis
calcifying fibrous pseudotumor of lung
pulmonary amyloidosis
pulmonary hyalinising granuloma
calcified pulmonary metastases
- osteosarcoma
- medullary thyroid carcinoma
