An X-ray image a: flaky blurred shadows with multiple small patches distributed in bilateral lungs with uneven density and ill-defined boundary; b-e pulmonary CT images: the enhanced irregular nodule in the left upper, and multiple point- and strip-like lesions scattered in the lower lobes. f contrast-enhanced CT: strip-like filling defect in the bilateral pulmonary arteries and their branches. Furthermore, the bilateral pleural effusion was revealed and no abnormality was discovered in the structure of the chest wall
