[Metastatic pulmonary choriocarcinoma and pulmonary arteriovenous aneurysm]

Pulmonary metastases from a uterine choriocarcinoma are rare in France. The authors report a case of a 42 years old patient who presented more than four years after her last pregnancy with a metastasis in the left lower lobe due to a uterine choriocarcinoma. There was a favourable outcome after combined treatment with chemotherapy and surgery. The patient had been in hospital eighteen months earlier for a spontaneous left haemothorax secondary to a ruptured intrapleural pulmonary arterio-venous aneurysm (AVV) of the left lower lobe which was treated by embolisation. The aetiology of pulmonary AVV are defined, and the pathophysiology of uterine carcinoma as well as the probable association and pulmonary vascular anomalies are discussed.
