We present the case of a 59-year-old man with a history of Graves’ disease status post radiation treatment presenting with cough and left lingual opacity on chest X-ray, confirmed to be thymic carcinoma with pericardial invasion and lymph node metastasis. We aim to discuss the presentation, treatment modalities and outcome associated with this rare tumour.
