Fig. 2Chest-X ray on admission day showed bilateral haziness, soft tissue mass on left mid lung field and the scoliosis of thoracic spine.
Fig. 3Chest computed tomography. A: dilated pulmonary arteries. B: ground-glass opacities on both lung fields and neurogenic tumor(black & white arrows)
Fig. 4Lung perfusion scan. Diffuse and severe perfusion decrease of left lung with wide photon deficient area at hilum, probably, due to effect of mediastinal shaft when considering chest computed tomography findings.
Fig. 5Cardiac catheterization. Normal pulmonary capillary wedge pressure and increased pulmonary arterial pressure are compatible with pulmonary arterial hypertension.
