CTICasesSilicone Injection for Pectus Deformity
Imaging findings
Chest radiograph and CT show large, dense, subcutaneous collections of amorphous, high-attenuation material (silicone) conforming to the anterior chest wall, placed historically to cosmeticially correct a pectus excavatum deformity.
Key takeaways
Cosmetic reconstruction using free silicone injection or custom silicone implants is an established treatment for pectus deformities. On chest imaging, this presents as dense subcutaneous material that should not be mistaken for a chest wall tumor, abscess, or calcified hematoma.
