A 39-year-old Caucasian woman, former smoker (6 pack-years), was referred to the outpatient clinic with an abnormal chest X-ray that revealed a large opacity obscuring the heart border (silhouette sign), as shown in Fig. 1. Chest tomography was performed and showed a large mass occupying much of the thoracic cavity. Histological evaluation of the lesion revealed findings that suggested a thymoma. Magnetic resonance imaging revealed no invasion of neighbouring structures. The patient underwent a bilateral thoracotomy, with excision of a 3.9kg thymolipoma. The chest X-ray performed after the surgery, as shown in the image, revealed complete expansion of both lungs.
