title: A rare case of primary pulmonary artery myofibroblastic sarcoma--imaging and pathologic features.
abstract: Primary myofibroblastic sarcomas of the pulmonary artery are very uncommon, but early detection is critical. Common clinical symptoms include shortness of breath, chest discomfort, and syncope. Patients diagnosed with a pulmonary tumor have a high risk of fatal pulmonary embolism. In this case study, we identified and diagnosed pulmonary artery myofibroblastic sarcoma in a young man by its imaging and pathologic characters. Surgery to excise the tumor was successfully performed and the operation was considered to have improved his prognosis. Postoperative examinations did not show any evidence of residual tumor, recurrence, or metastasis in the lungs or cardiac tissue. Based on the results of this case study, we concluded that the imaging and pathologic features of primary pulmonary artery myofibroblastic sarcoma can assist physicians in making a prompt diagnosis and an immediate surgical and treatment plan to greatly improve prognosis.
