Imaging findings
A complex vascular lesion with dense, coarse calcifications was noted on CT. Visible feeding vessels were observed originating from the internal mammary artery, with drainage into a thymic vein that subsequently connected to the brachiocephalic vein.
Key takeaways
Complex arteriovenous malformations in the chest can present with coarse calcifications and identifiable feeding and draining vessels. Detailed imaging can delineate the vascular supply and drainage, which is crucial for characterization and potential management.
