Pulmonary Arteriovenous Aneurysm as Manifestation of Osler-Weber-Rendu Syndrome

Pulmonary arteriovenous aneurysms (AVMs) are a common manifestation of Osler-Weber-Rendu syndrome. These can be associated with disastrous cerebral complications. Most cases can be treated with transcatheter embolisation. Very large aneurysms with multiple feeding vessels and previous failed embolisation may require surgical excision of the aneurysm.
