Introduction
Pulmonary embolism (PE) is a major cause of death worldwide (1). The risk factors are well described and classified by the European Society of Cardiology (ESC) in three categories : Strong, moderate and weak risk factors (2). The strong risk factors included generally : trauma of the lower limb or spinal cord, hip or knee replacement, hospitalization for heart failure or atrial fibrillation/flutter, myocardial infarction within previous three months and previous venous thromboembolism (2). Even if pulmonary embolism is rare in young adult, the causes are the same as in the adults (3). The recurrence of thromboembolism is generally associated to malignancy or thrombophilia (4). The most frequent occult malignancies during PE involved the lung, gastrointestinal tract, breast, and uterus (5). This is the reason why the screening of these cancers is systematic in the management of pulmonary embolism (2). Association between brain tumors and pulmonary embolism is rare. Some cases have been described mainly in perioperative period for craniectomy and the risk factors included : older age, motor deficit, high grade gliomas (6,7). We describe a rare case of recurrent pulmonary embolism in a young man with occult brain tumor. This case is important because it reinforces the need of critical and multidisciplinary assessment of thromboembolism in young patients before considering it as idiopathic.
