We concluded that the cigarette-lighter-shaped-device was after all an Insertable  Loop Recorder called Reveal Plus and produced by Medtronics®, with the purpose of monitoring patients at increased risk of cardiac arrhythmias. This device is leadless and MRI compatible and placed subcutaneously with minimally invasive procedure. It has a remote controller allowing in-office device programming and data retrieval using the Medtronic Software.

A middle-aged woman went to her breast cancer screening (every two year) and had 4-incidence mammograms. These were unremarkable except for the device seen on the MLO incidence and located in the upper outer quadrant closed to the left axilla.  

Although this location is most often chosen to place cardiac devices such as pacemakers or implantable cardioverter defibrillators sometimes chemotherapy catheters are placed here. Either way, both have wires and connections, the first to the right auricle and the former to superior cava vein or subclavia vein.  The lack of wires and the resemblance to a cigarette lighter or to a memory pen led to further investigation, as we had access to the following exams where the device was again seen.
