CTICasesDefibrillator Lead Insulation Disruption

Imaging findings
Serial radiographs over several years (2011 to 2014) showed progressive changes in a defibrillator lead. Initially intact, the insulation progressively thinned and then showed disruption near the generator.
Key takeaways
Defibrillator lead failures, including insulation disruption, can occur over time. While this specific instance was near the generator (an unusual location), it highlights the need for careful comparison of serial imaging to detect subtle changes in device integrity. The clinical significance of such findings, especially if the device remains functional, can be complex.
