Infarctus pulmonaires excavés révélant une hypertension pulmonaire post-embolique

Several etiologies are involved in the pathogenesis of cavitating pulmonary disease including neoplastic, infectious or inflammatory processes. Another is pulmonary infarction associated with venous thromboembolism. The lung cavities tend to be located peripherally and are the result of pulmonary embolism. We report the case of a woman with chronic thromboembolic pulmonary hypertension (CTEPH), associated with familial thrombophilia, revealed by cavitating pulmonary infarcts. CTEPH is sometimes diagnosed during an episode of recurrent pulmonary embolism following previously unnoticed lesions. Thrombophilias such as isolated elevated factor VIII are risk factors for CTEPH.
