[Pleural effusion in hereditary haemorrhagic telangiectasia: hemothorax or empyema?].

INTRODUCTION

In hereditary hemorrhagic telangiectasia the pulmonary arteriovenous malformations frequently lead to complications. In a case of pleural effusion in a patient with known pulmonary arterio-venous malformations, the first diagnosis to consider is a hemothorax even though alternatives such as empyema are possible.

CASE REPORT: We report the case of a 35-year-old woman with a known diagnosis of hereditary hemorrhagic telangiectasia with bilateral arteriovenous malformations, who was admitted to the emergency department with subacute dyspnoea and left thoracic pain. The clinical examination suggested a hemothorax. Pulmonary angiography was performed and showed an arteriovenous malformation in the left lower lobe. Embolisation was undertaken and at the same time a chest tube was inserted. Pus was evacuated leading to the final diagnosis of pleural empyema. Progress was good despite an episode acute respiratory distress due to a pulmonary embolism.

CONCLUSION

Pleural empyema is rarely described in the context of hereditary hemorrhagic telangiectasia with pulmonary arteriovenous malformations. In the case of pleural effusion this diagnosis should be considered even though hemothorax is more common.
