A 62-year-old woman was diagnosed with right lung adenocarcinoma. In addition, CT revealed 22 - and 9 -mm nodules in the anterior mediastinum and suprasternal fossa, respectively. The mediastinal tumor had a high SUV-max value, and the signal pattern on MRI suggested that the tumor originated from the thymus. All tumor markers were within normal limits, including soluble IL2-R. Right upper lobectomy and mediastinal tumor resection were performed. The final pathological examination revealed that both the mediastinal tumor and a nodule in the suprasternal fossa were diffuse large B-cell lymphoma. Malignant lymphoma cannot be ruled out irrespective of the signal pattern on MRI.
