This middle-aged woman was known to have a mycobacterium avium intracellulare infection and presented with haemoptysis. She underwent bronchial arterial embolisation, but continued to cough up blood. A CTA was performed in order to assess for possible pulmonary arterial supply to the lesion.
Type: Ultravist 370
Injection rate: 4 ml per second via an antecubital vein
Total volume: 60 ml
Bolus tracking: pulmonary outflow, 50HU above baseline
A cavitating lesion in the right lower lobe was detected. Blood supply via a pulmonary arterial branch was confirmed and two draining veins were detected. The bronchial communication was also well demonstrated.
The CT was able to accurately and quickly show the relevant anatomy as described. The patient was then transferred to the interventional suite for appropriate emblolisation.
