CTICasesIntercostal Artery Pseudoaneurysm secondary to Severe Scoliosis

Imaging findings
Chest radiograph revealed severe thoracic scoliosis and high-density material from previous endovascular treatment. CT demonstrated bilateral pleural effusions and a focal area of contrast density near the aorta, arising from an intercostal artery. Digital subtraction angiography confirmed an intercostal artery pseudoaneurysm, which appeared to be spilling contrast from a level below previous coils. MIP reconstructions helped visualize the intercostal artery origin.
Key takeaways
Severe thoracic scoliosis can induce chronic shearing stress on intercostal arteries, predisposing to pseudoaneurysm formation. These can present with acute, severe chest and back pain, and hemothorax. Endovascular embolization with coils is an effective treatment strategy for such pseudoaneurysms.
