Diagnosis: Migration of breast augmentation filler
Radiologic Findings: Fig 1. Chest PA shows mass-like lesions in the bilateral paratracheal area.
Fig 2-5. CT scans reveal infiltrative low-attenuating lesions involving bilateral breasts, bilateral supraclavicular fossae, mediastinum, and axillae.
Brief Review: Unlike silicone implants, subcutaneously injected fillers lack a barrier to keep the shape in place and prevent migration. There have been case reports of filler material migrating to the mediastinum, peritoneum, chest wall, axilla, and inguinal region. Clinicians should be aware of this condition because it looks like lymphoma on a chest computed tomography scan.

In our case, lymphoma was initially suspected and referred to our hospital. However, Chest CT scans suggested breast filler migration rather than lymphoma. PET-CT scan revealed no perceptible FDG uptake in this area. A surgical biopsy confirmed that the mass was foreign material.
