CTICasesChest Wall Desmoid Tumor Resembling a Breast Implant

Imaging findings
Chest CT and MRI show a well-circumscribed chest wall mass in the right breast region that mimics the contour of a breast implant capsule, showing heterogeneous signal intensity on T2-weighted MRI and focal bone destruction with cortical invasion into an adjacent rib.
Key takeaways
Desmoid tumors (deep fibromatosis) are benign but locally aggressive fibroblastic tumors that can arise in the chest wall, sometimes associated with prior surgical trauma or implants. Because they can grow to fill the fibrous capsule of a previous implant, they can clinically and radiographically mimic an implant or implant-related complication.
