A large pericardial cyst caused a 52-year-old man
Area of Science:
- Cardiology
- Thoracic Surgery
- Radiology
Context:
- Pericardial cysts are rare congenital mediastinal masses.
- Typically asymptomatic and found incidentally.
- Large cysts can cause significant symptoms like dyspnea.
Purpose:
- To report a case of a large pericardial cyst causing progressive dyspnea.
- To highlight diagnostic challenges and imaging modalities.
- To discuss the management of symptomatic pericardial cysts.
Summary:
- A 52-year-old man presented with dyspnea due to a 10 cm subpulmonary mass.
- Computed tomography (CT) revealed a water-like density mass.
- Video-assisted thoracoscopic surgery (VATS) confirmed a large pericardial cyst.
Impact:
- This case underscores the importance of considering pericardial cysts in the differential diagnosis of mediastinal masses.
- Accurate diagnosis relies on advanced imaging like CT and MRI.
- Surgical intervention may be necessary for symptomatic relief.
