Abstract:
Primary sarcomas arising from the trunk or branches of the pulmonary artery are exceedingly rare and usually diagnosed at autopsy. The authors report the case of a 31 year old man referred for investigation of recurrent syncope. Echocardiography, right ventriculography and the thoracic computed tomography led to early diagnosis of a pulmonary artery tumour and surgical resection. Histology revealed a primary sarcoma. The early postoperative course was uncomplicated but one month after surgery a local recurrence was diagnosed at routine echocardiographic examination. The syncopal symptoms recurred seven months after surgery and echocardiography showed tumour recurrence on the interventricular septum and in the pulmonary artery. A second palliative operation was attempted but was unsuccessful because of the size of the tumour.
