A Large Idiopathic Arteriovenous Malformation of the Right Lung, Which Was Mistaken for Lung Cancer

A 53-year-old male was admitted to the hospital because of retrosternal and epigastric pain radiating to the back. Radiologic images showed a homogeneous soft tissue mass in the right upper lobe that was initially misdiagnosed as a lung cancer. Fortunately, a careful Doppler examination identified two vascular structures within the lesion. This diagnostic study suggested the execution of a more appropriate computed tomography angiography (CTA). The examination confirmed the diagnosis of a simple pulmonary arteriovenous malformation (AVM). The patient underwent embolization of the arterial side of the AVM and finally a posterolateral mini-thoracotomy to remove the lesion.
