Pleural effusion revealing giant cell arteritis.

Pulmonary involvement is considered to be rare in giant cell arteritis (GCA), usually occurring in the course of the disease. We describe the case of a patient who developed left pleural effusion revealing GCA. Thoracic CT scan demonstrated an abundant left pleural effusion and a thickening of the aortic wall.

[Mediastinal teratoma with recurrent encysted pleural effusion].

A 25 year old man with no previous history was admitted for a recurrent right sided encysted pleural effusion. Thoracocentesis revealed an exudative lipase-rich-fluid. Because of the persistence of abundant pleural fluid after several thoracocentesis a diagnostic mediastinotomy was performed.
