We report the case of a 44-year-old male patient with bicuspid aortic valve, presenting with hemoptysis. Catheter angiography revealed an abnormal communication between bronchial and pulmonary artery, which remained undetected on computed tomography angiography. Angioembolization was done using polyvinyl alcohol and gelfoam particles. This is the first case in literature describing bronchial arteriovenous malformation associated with bicuspid aortic valve.

Ischemic stroke involving multiple artery territory with normal vessels gives a clue for an embolic stroke. Paradoxical embolization is a recognized cause of ischemic stroke. We describe a 48-year-old male who presented with acute onset giddiness, mild dysarthria, right hemiparesis, and ataxia. Clinical examinations indicated left cerebellar signs with right hemiparesis. Additionally, the patient had significant clubbing and mild cyanosis. A strong family history of epistaxis and hemoptysis was noted. His Magnetic resonance imaging of the brain showed acute left cerebellar and left frontal cortical infarct with normal vessels. The routine stroke and cardiac workup were normal. Chest X-ray showed bilateral lower zone opacities. Contrast-enhanced computerized tomogram (CT) of the chest showed bilateral pulmonary arteriovenous malformation. Paradoxical embolism due to pulmonary arteriovenous malformation resulted in ischemic stroke in our patient. He fulfilled all of the four criteria for diagnosing definite hereditary hemorrhagic telangiectasia. Our case highlights the importance of a systematic search for paradoxical embolism in a cryptogenic stroke.

There have been few reports of pulmonary arteriovenous malformations complicated by hemoptysis. Herein, we present our experience and provided a review of the literature. A man in his 80s came to our hospital with a chief complaint of hemoptysis, and a simple computed tomography showed a consolidation in the right lower lobe of the lung. He was treated for bacterial pneumonia, and his symptoms and a consolidation resolved, but similar episodes continued afterwards. About 18 months after the initial disease onset, the patient had hemoptysis and came to our hospital again. He was diagnosed with pulmonary arteriovenous malformation due to the presence of a lumpy, mass-like dilatation in the peripheral arteries. With the suspicion that the hemoptysis was caused by pulmonary arteriovenous malformations, the patient underwent coil embolization, and his symptoms gradually resolved. Computed tomography also showed improvement in shadowing. The hidden arteriovenous malformation was buried by a dense pulmonary field shadow; thus, it was diagnosed after a long time. This case highlights that pulmonary arteriovenous malformations should be considered in differentiating cases presenting with hemoptysis.
