Benign thymoma presenting as symptomatic pericardial tamponade

Area of Science:

• Cardiology
• Oncology
• Thoracic Surgery

Background:

• Pericardial effusion is a known, though uncommon, complication of thymoma.
• Pericardial tamponade, a life-threatening condition, has not been previously associated with benign thymoma.

Observation:

• A male patient presented with clinical signs and symptoms of pericardial tamponade.
• Diagnostic work-up was initiated to determine the underlying cause of the cardiac emergency.

Findings:

• The patient's condition was ultimately attributed to a previously undiagnosed benign thymoma.
• This finding establishes a novel association between benign thymoma and pericardial tamponade.

Implications:

• This case expands the spectrum of potential complications associated with benign thymoma.
• Clinicians should consider benign thymoma in the differential diagnosis of pericardial tamponade, particularly in patients with risk factors.
• Further research may elucidate the mechanisms linking thymoma to cardiac tamponade.
