Abstract:
A 15-year-old boy presented with central cyanosis with clubbing and dyspnoea on exertion. Cardiovascular examination did not reveal any abnormality. ECG was normal. Chest X-ray showed a normal sized heart with rounded opacities of variable size in the left upper lung field. Two-dimensional echocardiographic examination was normal. CT angiography showed a large complex lesion composed of serpiginous tubular structures involving the left upper and lingular lobe, suggestive of racemose tangle of blood vessels. A diagnosis of large complex arteriovenous (AV) fistula involving the left upper and lingular lobe was performed. This case reports a rare case of complex pulmonary AV fistula.

Overview of Pulmonary Circulation
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...
