Figure 1: Computed tomography (CT) scan of the chest. Axial image (A) shows a 2 × 3 cm mass in the anterior mediastinum and a tumour thrombus occluding the SVC and the azygos vein (arrows). On CT scan, the mediastinal mass does not have any connection either with the LBV or with the SVC. This unusual intravascular growth is due to the spread of the tumour into the LBV and SVC through the thymic...

Mesothelioma is a rare tumour and its radiological growth pattern varies. We report the case of a biopsy proven Malignant Pleural Mesothelioma (MPM) presenting as an anterior mediastinal mass in a platinum miner. The prognosis for this aggressive tumour remains poor, despite combination treatment modalities.

Thymoma is the commonest tumour of the anterior mediastinum in adults. Ectopic thymoma sometimes occurs, usually affecting the neck, mediastinal compartments, the lung and, very rarely, the pleura. We describe the case of a giant right-sided pleural thymoma (14 13 8 cm), preoperatively suspected to be a solitary fibrous tumour; a complete surgical resection was achieved and a postoperative diag...

Mediastinal bronchogenic cysts present problems in diagnosis and management.' 2 A smooth, rounded appearance of the radiological shadow and proximity to central airways suggests the diagnosis. Nevertheless, recent experience with computed tomography indicates that nearly half of the lesions studied appear to be solid in density, and even those that are fluid filled may sometimes be confused wit...

In this report we present a case ofprimary yolk sac tumour of the anterior mediastinum in which two dimensional echocardiography showed an extracardiac mass simulating a large pericardial effusion. Mediastinal yolk sac tumour is a rare germ cell neoplasm affecting mainly young men.' The most common presenting symptoms are dyspnoea, cough, and chest pain.2 The prognosis is usually poor, though i...
