Pulmonary artery fungal infection with imaging findings resembling pulmonary artery sarcoma.

A 67-year-old female patient was admitted due to "coughing and chest tightness" for more than 7 months. She had recurring chest tightness and shortness of breath after activities for more than 3 months, which worsened in the past 1 month. More than 7 months ago, the patient had a severe cough with a small amount of white sputum and chest tightness and discomfort, and visited a local hospital. The heart color Doppler ultrasound and other examinations were checked, and she was diagnosed with pulmonary embolism. Pulmonary artery CTA (CT angiography) showed the shadow of an intraluminal filling defect in the proximal main pulmonary artery. Therefore, a diagnosis of pulmonary embolism was made, with proximal tortuous stenosis of the left main pulmonary artery and distal expansion, which were considered to be congenital malformations.
