Pulmonary arteriovenous malformation: An uncommon disease with common presentation

A 45-year-old male presented with massive hemoptysis, clubbing in all limbs, disproportionate hypoxia and persistent ill-defined shadow in left lower zone in chest radiograph since his childhood. The patient received empirical anti-tuberculosis treatment and the chest X-ray finding was misinterpreted as tuberculoma. Subsequently, CT pulmonary angiography proved it to be a case of a simple type solitary pulmonary arteriovenous malformation with a saccular aneurysm in left lower lobe.
