Summary

Aortic dissection artifact on CT scans is common in adults but rare in children. This case highlights a false-positive diagnosis in a child due to aortic wall motion artifact.

Area of Science:

  • Radiology
  • Pediatric Imaging
  • Cardiovascular Imaging

Background:

  • Aortic dissection is a serious condition affecting the aorta.
  • CT angiography is a key diagnostic tool for aortic pathologies.
  • Recognizing imaging artifacts is crucial for accurate diagnosis.

Observation:

  • Motion artifact of the aortic wall can mimic aortic dissection on CT scans.
  • This artifact is well-documented in adult radiology.
  • Its presence in pediatric CT angiography is less recognized.

Findings:

  • The study presents a pediatric case with a false-positive CT diagnosis of aortic dissection.
  • The diagnosis was attributed to aortic wall motion artifact.
  • The patient was identified as being at risk for aortic dissection.

Implications:

  • Pediatric radiologists must be aware of this potential imaging pitfall.
  • Accurate interpretation of pediatric CT angiography is essential to avoid misdiagnosis.
  • Understanding motion artifacts improves diagnostic confidence in pediatric cardiovascular imaging.
