A 60-year-old man undergoes a routine chest radiograph which reveals a well-defined, smooth, lobulated 3 cm mass in the right cardiophrenic angle. On computed tomography, the lesion has fluid attenuation and does not enhance following contrast administration. What is the most likely diagnosis?
- A.Thymoma
- B.Pericardial cystCorrect answer
- C.Bronchogenic cyst
- D.Teratoma
Solution
Pericardial cysts are classic benign congenital lesions that most frequently occur in the right cardiophrenic angle (followed by the left cardiophrenic angle). On CT, they appear as well-circumscribed, thin-walled masses with fluid attenuation and no contrast enhancement.
