Thymoma

In this contrast thoracic CT scan of a middle-aged woman with newly diagnosed seropositive generalized myasthenia gravis, an abnormal thymic lesion (present in the anterior mediastinal compartment) could be seen arrow_1 (Figure 1). The patient was referred to the Cardiothoracic Surgeons where she received a thymectomy via an open sternotomy. The thymic specimen was sent for histo-pathological analysis and was confirmed to be a thymoma.

A chest radiograph (Figure 2) of the patient after the operation was performed and shows the presence of sternotomy wires arrow_1. Of interest, is that the right breast soft tissue shadow is lacking in the chest radiograph arrow_3. In fact, the patient also had a right mastectomy done few years ago for a breast carcinoma.
