Abstract:
Thymic carcinoma is a rare mediastinal tumor that is distinguished from malignant thymoma without cytologic atypia. We present two cases of thymic carcinoma with high uptake of Tl-201. Absence of Tl-201 uptake in a residual mass on the CT scan indicated a lack of tumor viability after the completion of therapy, which was verified by sequential needle biopsy. Tl-201 SPECT seems to be useful both in detecting thymic carcinoma and in assessing the therapeutic effect.
