Pulmonary arteriovenous malformation (PAVM) is a vascular anomaly of the lung. These lesions which are usually congenital can lead to life threatening complications later in life. It can occur primarily or in association with hereditary haemorrhagic telangiectasia. They are very rare during pregnancy but can cause life threatening complications. We present the case report of a young woman with acute onset of a large hemothorax during the third trimester of pregnancy. Multiple PAVM were noted in the lower lobe of the lung. There was intrauterine death and foetus was evacuated. She underwent thoracotomy and segmental resection of multiple lesions. PAVM should be considered in young women with acute onset of a spontaneous hemothorax and should be managed emergently. Treatment should follow a multidisciplinary approach and complications of PAVMs can be managed effectively with surgery.
