    A-21-year old woman presented with exertional breathlessness, fatigue and episodic mild haemoptysis for the past 7 months. Peripheral arterial oxygen saturation (SpO2) was 87% on room air. Clubbing and central cyanosis were present. There was no improvement in SpO2 and cyanosis with supplemental oxygen therapy. Chest radiograph revealed a heterogeneous opacity in right upper zone (figure 1A). CT pulmonary angiogram revealed diffuse pulmonary A-V malformation (PAVM) involving apical and anterior segments of right upper lobe with multiple pulmonary arterial branches directly communicating with the pulmonary veins (figure 1B). A subcentrimetric area of diffusely enhancing soft tissue attenuation was seen alongside right lower end of trachea adjacent to PAVM, for …
