Computed Tomography of Solitary Pulmonary Nodules

  • P. Armstrong


The possible diagnoses of a solitary pulmonary nodule are numerous (Table 1), but over 95% fall into one of three groups:
  1. 1.

    Malignant neoplasm, either primary or metastatic

  2. 2.

    Infectious granulomas, either tuberculous or fungal

  3. 3.

    Benign tumors, notably hamartomas.
