Calcification in intralobar pulmonary sequestration (ILPS) is rare. A recent case showed a non-enhancing vessel on CT, later found to be a thrombosed and calcified artery, explaining the unusual radiographic findings.

Area of Science:

  • Radiology
  • Thoracic Surgery
  • Pathology

Background:

  • Intralobar pulmonary sequestration (ILPS) is a congenital lung malformation.
  • Typical imaging findings include a systemic feeding artery on computed tomography (CT).
  • Radiographically evident calcification within ILPS is exceptionally rare.

Observation:

  • A case of ILPS presented with unusual imaging characteristics.
  • CT revealed a tubular structure that did not enhance with contrast.
  • This non-enhancing structure was initially not identified as a feeding artery.

Findings:

  • Pathological examination confirmed the tubular structure was a systemic artery.
  • The artery had undergone thrombosis, organization, and subsequent calcification.

  • This process explained the presence of calcification on both plain chest radiography and CT.

    • Implications:

    • This case expands the understanding of atypical presentations of ILPS.
    • It highlights the importance of considering vascular complications like thrombosis in ILPS.
    • The findings emphasize the correlation between pathological processes and radiographic features in diagnosing ILPS.
