Overview
The tumor is generally located inside the thymus, and can be calcified. Increased vascular enhancement can be indicative of malignancy, as can be pleural deposits.
CT Scan
When a thymic mass is identified, the made is achieved with histology (obtaining a tissue sample of the mass). When a thymoma is suspected, a CT/CAT scan is generally performed to estimate the size of the tumor, and can be biopsied with a CT-guided needle. There is a small risk of pneumomediastinum, mediastinitis and the risk of damaging the heart or large blood vessels. The final diagnosis is made by removing the thymus. Pathological investigation of the specimen will reveal if the tumor was benign or malignant, although the initial biopsy is usually indicative.[1]
