a Ultrasound revealed a large septated seroma (white arrow), which was aspirated the following day. Cytology confirmed BIA-ALCL. Ultrasound has a sensitivity of 84% and specificity of 75% for detecting an effusion. These figures are similar or better than CT or magnetic resonance imaging (MRI) in effusion detection [7]. b MRI provides characterisation of the implant’s capsule, defining enhancement and thickening [14, 15]. This makes it the modality of choice for defining the implant capsule (white arrow) [7]. BIA-ALCL typically presents as a delayed, non-infective fluid collection surrounding the implant (red arrow) or its surrounding scar capsule, with or without evidence of capsular rupture [13]. c Staging CT revealed a small to moderate effusion adjacent to both breast implants (white arrows)
