Response of pulmonary artery intimal sarcoma to surgery, radiotherapy and chemotherapy: a case report.
BACKGROUND
Pulmonary artery intimal sarcoma is a rare disease with no characteristic symptoms. It is difficult to diagnose early and is frequently misdiagnosed as a pulmonary embolism.


METHODS
Here we report a case of pulmonary artery intimal sarcoma in a 54-year-old woman presenting with complaints of shortness of breath on exertion. Echocardiography and a computed tomography scan showed that the right pulmonary artery trunk was blocked by a low-density mass. The patient was diagnosed with pulmonary artery intimal sarcoma by pathology and a complete mass resection was performed. After experiencing 10 months of disease-free survival, she was re-admitted because of the recurrence and metastasis of the tumor. Radiotherapy and chemotherapy were performed; however, only limited success was achieved. The patient died 15 months after the initial onset of symptoms.


CONCLUSIONS
Some patients with intimal sarcoma of the pulmonary artery can benefit from radiotherapy and chemotherapy as well as surgery.
