CTICasesSpontaneous intercostal artery hemorrhage
Imaging findings
Chest radiograph and CT show a large, rapidly expanding right extrapleural soft tissue mass representing a hematoma, associated with active extravasation from an intercostal artery that was successfully managed with transcatheter embolization, in a patient with systemic lupus erythematosus.
Key takeaways
Spontaneous, non-traumatic chest wall hemorrhage from an intercostal artery is a rare vascular emergency that can occur in patients with underlying vasculopathy, liver disease, or on anticoagulants. Transcatheter arterial embolization is the treatment of choice.
