Aneurysms of the ductus arteriosus are rare but dangerous. This study reviews radiologic findings and successful treatments for these mediastinal masses, emphasizing CT and angiography for diagnosis.

Area of Science:

  • Cardiovascular Medicine
  • Radiology
  • Pediatric Surgery

Background:

  • Aneurysm of the ductus arteriosus is a rare condition with a high risk of rupture.
  • Diagnosis can be challenging due to its location and potential for obscuration by mediastinal structures.

Purpose of the Study:

  • To describe the radiologic findings of ductus arteriosus aneurysms.
  • To review diagnostic and treatment strategies based on literature and clinical experience.

Main Methods:

  • Literature review and case series of 5 patients.
  • Radiologic evaluation including conventional radiology, ultrasonography, computed tomography (CT), and angiography.

Main Results:

  • A left-sided mediastinal mass is a consistent finding, unless rupture has occurred.

  • CT with contrast enhancement is an excellent noninvasive diagnostic tool.
  • Angiography is crucial for assessing ductal end patency or occlusion.

    • Conclusions:

    • Accurate diagnosis of ductus arteriosus aneurysm requires a combination of imaging modalities.
    • Differential diagnosis must exclude other mediastinal tumors and normal ductal widening in neonates.
    • Surgical treatment is generally successful.
