Case 1. A 60-year-old woman. The patient was histopathologically diagnosed with PTTM accompanied by breast cancer at autopsy. (A) Lung CT revealed multiple small bilateral nodules. (B, C) Lung PBV images on dual-energy CT demonstrated bilateral subsegmental defects in the lung.

On day 14, lung CT revealed multiple small bilateral nodules (Fig. 1A). Lung PBV images obtained by dual-energy CT demonstrated multiple bilateral subpleural wedge-shaped defects in the lung (Fig. 1B and C).

Case 2. A 40-year-old woman with suspected PTTM due to gastric adenocarcinoma and improvement on chemotherapy. (A, B) Lung CT revealed multiple small bilateral nodules and ground-glass opacities (GGOs). (C) A CT pulmonary angiogram showed no evidence of pulmonary embolism. (D-F) Lung PBV images demonstrated small bilateral defects in the pleural margins.
