Intrapulmonary lymph nodes (IPLNs) can appear as pulmonary nodules. Thin-section CT improves visualization of IPLN borders and relationships, aiding diagnosis when differentiating from malignant nodules.

Area of Science:

  • Radiology
  • Pulmonology
  • Thoracic Imaging

Background:

  • Intrapulmonary lymph nodes (IPLNs) are increasingly recognized as potential causes of pulmonary nodules.
  • Accurate identification and characterization of IPLNs are crucial for differential diagnosis and avoiding unnecessary interventions.

Purpose of the Study:

  • To evaluate CT findings of pathologically proven IPLNs.
  • To discuss the diagnostic utility of thin-section CT and contrast-enhanced CT for IPLNs.

Main Methods:

  • Retrospective review of CT findings in 14 patients with pathologically confirmed IPLNs (18 nodules).
  • Analysis of conventional CT, thin-section (2 mm) helical CT, and contrast-enhanced helical CT findings.
  • Correlation of CT imaging features with pathological results.

Main Results:

  • IPLNs were typically located below the carina and near the pleura.
  • Thin-section CT enhanced visualization of nodule borders and relationships, especially those obscured on conventional CT.
  • Contrast-enhanced CT showed enhancement in all evaluated IPLNs (36-85 HU), but this was not specific for distinguishing from malignant nodules.

Conclusions:

  • IPLNs should be considered in the differential diagnosis of peripheral pulmonary nodules.
  • Thin-section CT is valuable for delineating IPLN characteristics and their relationship to surrounding structures.
  • Distinguishing IPLNs from malignant nodules based solely on contrast enhancement is challenging, necessitating careful CT observation and consideration of size changes for potential surgical intervention.
