患者,男,68岁。咳嗽伴痰血20d,起初未予重视,后至当地医院就诊,行胸部CT提示右下肺占位伴右下肺阻塞性炎症。为求进一步治疗,遂至我院行胸部CT检查示右肺中叶外侧段见一结节影,最大径约1.6cm,境界清晰,可见分叶征,增强示中度强化;右肺下叶支气管狭窄,远端呈铸型密度增高影,周围境界欠清(见内页4图1)。支气管镜检查示右下叶支气管基底段开口见新生物堵塞,表面白 Patient, male, 68 years old. Cough with blood stasis for 20 days was initially ignored. After visiting a local hospital, a chest CT scan was performed to show that the right lung occupying location was associated with obstructive inflammation in the right lower lung. For further treatment, chest CT examinations in our hospital showed a nodules in the lateral segment of the right middle lobe of the right lung. The maximum diameter was about 1.6 cm. The border was clear. The lobulation sign was shown, and the enhancement was moderate; the right lung was inferior bronchial stenosis. The density of the mold at the distal end is increased, and the surrounding state is less clear (see Figure 1 on page 4). Bronchoscopy revealed new biological blockage at the basal segmental opening of the right lower lobe bronchial surface.
