Interim investigations with MRI neck and Positron Emission Tomography (PET)-CT demonstrated locoregional recurrence of squamous cell carcinoma and uptake within the pulmonary cavity attributed to metastases. The bronchial arteries are the most common source of haemorrhage, with pulmonary arteries second, accounting for 6%–11% of cases.2 3 Pulmonary artery pseudoaneurysms are associated with cavitating infections or malignancy, usually primary lung cancer, and rarely due to metastases.4 5 No difference in pseudoaneurysm morphology or response to treatment has been identified for different types of malignancy. When a pseudoaneurysm is evident on CT but not on catheter angiography (type D), empirical targeted embolisation based on CT findings may be considered.7 Where a massive haemoptysis pathway is in place, the patient may be transferred from the CT scanner to the interventional radiology suite to receive prompt endovascular treatment.
