Age - Risk of malignancy increases with age
  • Risk of 3% at age 35-39 years
  • Risk of greater than 50% in patients older than 60 years
  • Usually, nodules are identifiable by the time they are 8-10 mm on chest radiographs
  • size alone is a pior predictor in a give individual

  • The growth rate refers to the doubling time of a nodule, ie, doubling in volume.
  • volume of a sphere equals 4/3 pr3; therefore, a 26% increase in diameter on a chest radiograph represents one doubling in volume. ( 2d on x-ray, not 3 d)
  • For example, an increase from 1-1.3 cm equals one doubling. A 1-2 cm increase relates to an 8-fold increase in volume.
  • Bronchogenic carcinomas usually have a doubling time of 20-400 days
  • Doubling times shorter than 20-30 days are seen in infections, infarction, lymphoma, or fast-growing metastases.
  • Doubling times greater than 400 days are typically benign
  • Absence of change in size of a nodule over 2 years is highly suggestive of a benign lesion.
  • of course exceptions occur. CXR may not accurately dectecta 3mm change

In benign lesions, 5 patterns of calcification are seen commonly, including diffuse, central, laminar, concentric, and popcorn (chondroid) calcifications.

The popcorn pattern typically is described in hamartomas. A stippled or eccentric pattern is seen most commonly in malignant lesions

calcifications--more likely b9 but 10% of malignant nodules have em


densitometry not commonly used. fat within a nodule---hamartomas likely

Procedures:
  • Biopsy
    • bronchoscopically or via transthoracic needle aspiration (TTNA). Because the yield from bronchoscopy is only 10-20% foe nodule< 2 cm in diameter, bronchoscopy and transbronchial needle aspiration (TBNA) may be helpful when the lesion is either endobronchial in location or near a large airway. TBNA may also be helpful in sampling the mediastinal nodes.
    • TTNA--> accuracy of 90-95% when the lesion is 2 cm or l>, although the diagnosis is less accurate (60-80%) in lesions smaller than 2 cm. Confirming a specific benign diagnosis is more difficult (~70% accuracy); therefore, most lesions are characterized as nondiagnostic following TTNA.
  • management ---if malignancy suspected REMOVE

separation from parents, punishment,mutilation,
conception of illness in chaildren..when they become ill: may interpret illness as punishment often have all sorts of misconceptions about what is wrong wid them
untill age of 5: children usually have no conception of death as an irreversible process
only after age 8 or 9:children really understands that death is universal,invitable,and irreversible
