II. Definitions

  1. Lung Nodule
    1. Spherical opacity on xray <3 cm in diameter
    2. Completely surrounded by aerated lung
  2. Solitary Lung Nodule
    1. Isolated, single Lung Nodule
  3. Lung Mass
    1. Lung Lesion >3 cm diameter
    2. Considered to be Lung Cancer until proven otherwise
  4. Multiple Lung Nodules
    1. More than 10 diffuse Lung Nodule

III. Epidemiology

  1. More than 1.5 Million Lung Nodules are identified on lung imaging each year in U.S. (5% are malignant)
  2. Lung Nodule Incidence
    1. Chest XRay: 0.2% of all Chest XRays identify a Lung Nodule
    2. CT Chest: 13-15% of all scans identify a Lung Nodule

IV. Background

  1. Obtain CT Chest to further evaluate Lung Mass identified on Chest XRay
  2. Evaluation below is based on the CT Chest
  3. Compare findings to prior imaging (critical!)

V. Precautions

  1. Screening for Lung Nodules even in high risk groups (Tobacco users) has low yield of malignancy

VIII. Imaging: Modalities

  1. Chest XRay (PA and lateral)
    1. Nodules at 5 mm may be visualized
    2. Poor Test Sensitivity (high False Negative Rate)
    3. Nodules often noted as incidental XRay finding
  2. CT Chest (thin slice)
    1. Greater Test Sensitivity and Test Specificity than Chest XRay
    2. CT is a first-line test in evaluation of Solitary Lung Nodules found on Chest XRay
  3. FDG-PET
    1. High Test Specificity and Test Sensitivity for Solitary Lung Nodules >8-10 mm
    2. Indicated when indeterminate findings persist on CT or findings discordant with estimated cancer risk
    3. False Positive uptake by some inflammatory or infectious Nodules
  4. MRI Chest
    1. Not recommended in evaluation of Solitary Lung Nodule

IX. Imaging: Re-assuring imaging findings suggestive of BENIGN Lesions

  1. Benign calcification patterns (central, concentric, popcorn-pattern, diffuse or complete)
  2. Smooth, solid lesions
  3. Dominant Nodule
  4. Location at the perifissure or subpleural
  5. Small lesions <6 mm
  6. Lesion doubling time <30 days (more consistent with infection)
  7. Lesion doubling time >400 days (slower growth)

X. Imaging: Red flag findings on CT Chest (suggestive of malignancy)

  1. Nodule size >8 mm
    1. Contrast with benign lesions which are typically <5 mm in size
  2. Irregular border

    1. Non-enhancing lesion has 97% Negative Predictive Value for cancer
    2. Swenson (2000) Radiology 214: 73-80 [PubMed]
  7. Non-calcified lesion (or eccentric calcification)
    1. Non-calcified, ground-glass or eccentrically calcified lesions are a risk for malignant Nodules
    2. Other Calcification patterns (central, concentric, popcorn-pattern, diffuse or complete) suggest a benign lesion
  8. Semi-solid or subsolid Nodules (includes ground-glass appearance)

  2. Approach to surveillance imaging for small Nodules
    1. Unless otherwise specified, use low-dose, non-contrast CT Chest for surveillance (lower radiation)
    2. Malignant Nodules double in volume within 400 days
      1. A Lung Nodule without change over 2 years is considered benign
      2. Exception: Ground glass lesions have slower doubling time and require longer observation
    3. High risk patients have Lung Cancer risk factors
      1. Tobacco Abuse history
      2. Age >65 years old
      3. Malignancy history
  3. Small Nodule <6 mm
    1. Low risk patient
      1. Fleischner: Require no further follow-up for either single or multiple Nodules <6 mm
      2. ACC 5-6 mm: Chest CT at 12 months and no further follow-up if stable
    2. High risk patient
      1. Fleischner: Optional follow-up Chest CT in 12 months for either single or multiple Nodules
      2. ACC <=4 mm: Chest CT at 12 months and no further follow-up if stable
      3. ACC 5-6 mm: Chest CT at 6-12 months and repeat at 18 to 24 months if stable

    2. Consider repeat Chest CT at 2 and 4 years in high risk patients
    3. Management is based on most suspicious Nodule
    4. Discuss with pulmonology, thoracic surgery or radiology for CT surveillance versus Nodule biopsy
