Silicone-induced lymphadenopathy mimicking recurrence of breast cancer on positron emission tomography-computed tomography, correctly diagnosed on ultrasound.

Silicone-induced lymphadenopathy is a rare complication associated with silicone breast implants. It is usually asymptomatic and found incidentally during imaging. We report a case of silicone lymphadenopathy in a patient who had undergone a mastectomy and breast reconstruction for breast cancer. During follow-up, a positron emission tomography-computed tomography examination revealed lymph nodes that were suspicious for cancer recurrence. However, sonography was able to correctly diagnose silicone-induced lymphadenopathy and exclude cancer metastasis.

Angioplasty and stenting for the proximal anastomotic stenosis of a brachio-axillary bypass graft using a helical interwoven nitinol stent: A case report.

RATIONALE: Thrombosis due to anastomotic site stenosis is the most common complication in patients with brachio-axillary arteriovenous graft (AVG). Intravascular stent placement may play a special role in the salvage of dialysis grafts that have been previously performed percutaneous angioplasty or surgical procedure on the graft. Herein, we applied a novel stent named Supera which has a high degree of flexibility and resistance to external compression for treating a patient with recurrent venous anastomotic stenosis of brachio-axillary AVG. PATIENTS CONCERNS AND DIAGNOSES: We report a case of the patient with end-stage renal disease who presented with brachio-axillary AVG malfunction. INTERVENTIONS: The patient underwent repeated percutaneous angioplasty with thrombectomy for total graft occlusion, and we placed the Supera stent to salvage the graft. OUTCOMES: Postprocedural Doppler ultrasonography did not show any restenosis on the 1- and 3-month follow-up periods, and average flow volume in the stent was >1000 mL/min. And he has been on dialysis for 6 months without any problems after stent placement. LESSONS: The Supera stent is a useful treatment option of interventional procedure for recurrent venous anastomotic stenosis of brachio-axillary AVG in the clinical practice.
