Chief ComplaintChest discomfort & dyspnea for 1 month.

Diagnosis: Thymoma at Cardiophrenic Angle
Radiologic Findings: Chest PA and right lateral views show a huge homogeneous opacity involving lower half of the right anterior hemithorax.
Chest CT scan reveals a huge, heterogeneously enhancing solid mass in the right anterior mediastinum.
Brief Review: Thymoma shows vary in size from very small to larger than 20 cm in diameter. Most thymomas arise in the upper anterior mediastinum, but they may project into the adjacent middle or posterior mediastinum. They are usually found anterior to the ascending aorta above the right ventricular outflow tract and main pulmonary artery, and project into a hemithorax; less commonly they may extend to both sides of the midline. A few are situated in the lower third of the mediastinum and occasionally as low as the cardiophrenic angles. A thymoma entirely in the middle or posterior mediastinum is rare but is reported.
