Postoperative mediastinal masses. Report of two cases

Area of Science:

• Cardiovascular Imaging
• Thoracic Surgery
• Diagnostic Radiology

Background:

• Mediastinal masses can present as diagnostic challenges, potentially mimicking cardiovascular abnormalities on chest radiographs.
• Patients with a history of cardiac surgery, particularly for congenital heart lesions, are at higher risk for misdiagnosis due to mediastinal masses.
• The differential diagnosis of mediastinal masses requires careful consideration, especially in post-surgical patients.

Observation:

• Two cases are presented where mediastinal masses simulated cardiovascular disease.
• The masses caused apparent cardiac or vascular enlargement on chest radiographs.
• Symptoms and signs were attributed to compression of the heart or great vessels.

Findings:

• Mediastinal masses can lead to misinterpretation of cardiac and vascular structures on imaging.
• Prior mediastinal surgery may be a contributing factor to the development of these masses.
• The clinical presentation can closely resemble primary cardiovascular pathology.

Implications:

• Increased awareness is needed among clinicians to differentiate mediastinal masses from true cardiovascular disease, particularly in post-operative patients.
• Diagnostic protocols may need refinement to include thorough evaluation for mediastinal pathology in relevant patient populations.
• Accurate diagnosis of mediastinal masses is crucial to avoid unnecessary cardiac interventions and ensure appropriate management.
