Overview

Computed Tomography scan may be diagnostic of thymoma. The tumor is generally located inside the thymus, and can be calcified. Increased vascular enhancement can be indicative of malignancy, as can pleural deposits.

CT Scan

When a thymoma is suspected, a CT/CAT scan is generally performed to estimate the size of the tumor. Key CT scan findings in thymoma include:

• Smooth or lobulated border that is partially or completely outlined by fat
• Homogeneous soft tissue mass
• Fibrosis, cysts, hemorrhage or necrosis may be seen as decreased attenuation
• Amorphous, flocculent central/curvilinear peripheral calcification
