Implant deformity on screening mammography, an unusual presentation of breast implant associated lymphoma.

Breast implant associated anaplastic large cell lymphoma (BIA-ALCL) is a rare condition related to textured breast implants. Recognition of characteristic imaging and pathological features are important, given the absence of symptoms can delay diagnosis, as illustrated by this case. Late-onset peri-implant effusion is commonly encountered whilst an associated mass or lymphadenopathy are rare. Clinical and radiological suspicion enables dedicated pathology work-up for diagnosis. Ultrasound is vital for initial work-up whilst MRI and PET-CT assist in staging. Surgical explantation is followed by adjuvant chemo-radiotherapy according to disease extent.
