Presentation
Chest pain and shortness of breath. D-dimer 4000.
Patient Data
Anterior mediastainl mass measuring soft tissue density with irregular margins. No lymphadenopathy. No pulmonary embolus. Lungs are clear.
Moderate FDG uptake in the right anterior mediastinal mass. Uptake elsewhere is physiological with no evidence of remote disease.
Case Discussion
The differential for this anterior mediastinal mass is lymphoma, germ cell tumor and thymoma. Given its homogeneous appearance, and that it is relatively small and lobulated a thymoma is most likely.
The patient proceeded to resection of the mass, with histology demonstrating a thymic carcinoma that was completely excised.
There are no local aggressive features or metastatic disease on this CT to suggest the final diagnosis.
