Pure pulmonary arterial tumour embolism--a rare cause of pulmonary infarction.

Pulmonary vascular involvement in the natural course of spread of malignant tumours can produce respiratory distress and often manifests as lymphangitis carcinomatosis or carcinomatous arteriopathy. Pulmonary infarction due to arterial tumour embolism is infrequent. This is a report of a treated case of cervical cancer in middle-aged woman who presented after three years with infarction of the lungs following arterial tumour emboli.
