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
