Nexplanon removal from intramuscular implantation in biceps: case report.

Contraceptive implant devices are relatively safe devices, but complications arise when implants become nonpalpable, and cannot be safely removed. In this case report, we describe the location of an implant in the subfascial plane of the upper arm, the diagnostic imaging findings we encountered during the workup, and the procedure necessary to remove it. We demonstrated that if the device is in close proximity to the fascia, it may be difficult to distinguish from the fascia on magnetic resonance imaging. Nonetheless, fluoroscopy and ultrasound easily distinguished the device from the surrounding tissue and allowed localization intraoperatively.
