Abstract
Intrathoracic mesothelial cysts are congenital lesions due to an abnormal development of the pericardial coelom. They are generally unilocular and can develop in various sites. We describe a case of multicystic lesions in the anterior mediastinum of a 53-year-old woman discovered in a context of an encysted pleural effusion. Chest computed tomography (CT) scan revealed multiple cystic lesions in the anterior and posterior mediastinum. Surgery was carried out and histopathology and immunohistochemistry confirmed the diagnosis of multiple coelomic cysts of the mediastinum.
Highlights
Primary cysts of the mediastinum regroup bronchogenic cysts, enteric or duplication cysts, mesothelial cysts, thymic cysts, and thoracic duct cysts [1]

Summary
Primary cysts of the mediastinum regroup bronchogenic cysts, enteric or duplication cysts, mesothelial cysts, thymic cysts, and thoracic duct cysts [1]. Coelomic cysts are rare with mesothelial origin. They are often discovered incidentally but sometimes with indistinct symptoms in varying parts of the body. They are generally unilocular and can increase in various sites [2]. Mediastinal multicystic mesothelial cysts have been rarely reported
