title: Pulmonary haemangiosarcoma with main pulmonary artery thrombosis imitating subacute pulmonary embolism with infarction.
abstract: We report a patient with subacute pulmonary hypertension caused by unilateral massive pulmonary artery thrombosis due to a pulmonary haemangiosarcoma of the lower lobe with pulmonary arterial and bronchial invasion. The patient was misdiagnosed as having subacute pulmonary embolism and underwent thrombolytic therapy complicated by severe pulmonary haemorrhage. The imaging features of pulmonary artery thrombosis with underlying malignancy and their differential diagnosis are discussed.
