The chest spiral computed tomography with intravenous contrast showed a 130 x 160x 160 mm heterogeneous fat-containing soft tissue mass arising from anterior mediastinum with complete left lung collapse and contralateral mediastinal shift with no evidence of peripheral organs invasion or adjacent bony chest wall destruction or encasement or involvement of major mediastinal vessels (Fig. 1).

The open biopsy result was a yellow tissue with elastic consistency on its macroscopy, and its microscopy was abundant mature adipose tissue with less amount of mature thymus tissue (10% of total tissue) without any evidence of malignant changes, as a result, based on open biopsy, the diagnosis of thymolipoma was made, and tumor excision was recommended (Fig. 2).

The chest x-ray (Fig. 3) unveiled diffuse opacification of the left Hemithorax with the contralateral mediastinal shift. After ten days of rehabilitation, the left lung expanded entirely (Fig. 3), and the patient was discharged home without any complications.
