Incidence of Internal Mammary Lymph Nodes with Silicone Breast Implants at MR Imaging after Oncoplastic Surgery

Abstract

q RSNA, 2015 Purpose:To assess the incidence of benign and malignant internal mammary lymph nodes (IMLNs) at magnetic resonance (MR) imaging among women with a history of treated breast cancer and silicone implant reconstruction. Materials and Methods:The institutional review board approved this HIPAA-compliant retrospective study and waived informed consent. Conclusion:IMLNs identified at implant-protocol breast MR imaging after oncoplastic surgery for breast cancer are overwhelmingly more likely to be benign than malignant. Imaging follow-up instead of immediate metastatic work-up may be warranted.q RSNA, 2015

Axillary Silicone Laden Lymph Nodes: an Unusual Cause of Lymphadenopathy Case Report

“…There are no current guidelines on monitoring for lymphadenopathy in patients with breast augmentation. However, guidelines are in place for monitoring for breast implant rupture starting with MRI screening every 3 years after initial breast augmentation followed by every 2 years thereafter [10]. Due to majority of implant ruptures occurring after 11.5 years, guidelines should consider monitoring for silicone lymphadenopathy around this time range.…”

Silicone implant incompatibility syndrome: Mimicking metastases on fluoro-deoxy-glucose positron emission tomography–computed tomography in a treated case of carcinoma breast

“…Few cases reported in the literature with false-positive finding on FDG PET-CT due to SIIS are summarized in Table 1 . [ 8 9 10 11 12 13 ]…”

Metastatic internal mammary lymph nodes or mimickers on parasternal ultrasonography: focusing on their distribution and depth

“…The status of IMN can influence the clinical pathway of breast cancer patients because IMN metastases in breast cancer patients are associated with poor prognosis (9). Pathological confirmation of LNs prior to definitive therapy is important, because normal IMNs may appear incidentally on MRI or PET scans due to physiologic change (10)(11)(12)(13). Although the diagnostic performance of US versus PET for detecting metastatic IMNs has been investigated recently (14), US findings of metastatic IMNs have not been adequately described yet.…”
