Imaging findings
Post-procedural CT immediately after a CT-guided lung biopsy demonstrates a small pneumothorax along with a substantial volume of alveolar hemorrhage. The blood is seen pooling and layer-forming inside the pre-existing, large emphysematous spaces of the adjacent lung parenchyma.
Key takeaways
Pulmonary hemorrhage is a well-known complication of CT-guided lung biopsies, particularly in patients with severe underlying emphysema. In these patients, the extravasated blood often tracks into and pools within nearby emphysematous bullae, creating fluid levels that can mimic pre-existing cavitary lesions or abscesses on subsequent imaging.
