Abstract
A 30-year-old woman was referred to our department for multidetector computed tomography (MDCT) with a complaint of dyspnea. Her chest radiography findings were unremarkable. Wide area detector CT Angiography and contrast-enhanced CT scan revealed an enhancing cluster of tubular structures in the inferior lingular segment of the left upper lobe [1, 2]. Coronal maximum intensity projection (MIP) (Figure A) and three-dimensional volume-rendered CT images (Figures B, C) revealed a Pulmonary Arteriovenous Malformation PAVM with a feeding artery, an aneurysmal part, and a draining vein.

PAVMs can potentially affect any part of the lung, there is a recognized predilection toward the lower lobes (50-70%) [5]
Patients with PAVMs may have a variety of complications, including cyanosis, high-output congestive cardiac failure, polycythemia, and paradoxical cerebral embolism [6]
Summary
Of patients with a single PAVM and at least 50% of patients with multiple PAVMs have HHT [4]. PAVMs can potentially affect any part of the lung, there is a recognized predilection toward the lower lobes (50-70%) [5].
