We report a case of a 29-year-old female with a history of asthma, post-partum ARDS, and pulmonary hypertension who presents with severe shortness of breath. The patient describes her shortness of breath as progressive over the past 10 years. Chest radiography and CT angiography of the thorax showed findings consistent with fibrosing mediastinitis with severe stenosis of the left main pulmonary artery. This resulted in appearance of unilateral absent left lung perfusion on quantitative Tc-99-MAA perfusion and Xe-133 ventilation (V/Q) scan.
我们报告一例29岁女性病例，该患者有哮喘、产后急性呼吸窘迫综合征和肺动脉高压病史，现出现严重气短。患者称其气短在过去10年中呈进行性加重。胸部X线摄影和胸部CT血管造影显示的结果符合纤维性纵隔炎，伴有左主肺动脉严重狭窄。这导致在定量Tc-99-MAA灌注和Xe-133通气（V/Q）扫描中出现左肺单侧灌注缺失的表现。
