Purpose or Case Report: The threat of button battery ingestion persists as many electronic devices utilize the batteries for power. Although there are variable sequalae after button battery ingestion and removal, some serious complications that can result include necrosis, ulceration, fistula development, and heavy metal toxicity. Prompt removal of a button battery is essential to decrease these serious effects on the patient. Even after removal of a button battery, sequela of ingestion can be present that requires imaging follow up and further management. At our university hospital, we have implemented an MRI protocol to evaluate an affected organ system after ingestion and removal of a button battery. Here, we discuss our findings and review how images obtained from the protocol have impacted patient follow-up and management.

CONTENT ORGANIZATION:
1) Overview and epidemiology of button battery ingestion.
2) Sequela of button battery ingestion and concerning imaging features status post button battery removal.
3) Discuss current literature and recommended MRI protocols.
4) Review images obtained through the implemented MRI protocol.
5) Brief discussion of benefits and how to implement an MRI protocol.

SUMMARY:
The major teaching points will include:
1) An eclectic array of MRI images after the removal of a button battery to provide a baseline understanding of benign and alarming findings.
2) A detailed review of concerning imaging features by organ system after removal of a button battery.
3) How to develop and implement an MRI protocol to image patients after removal of a button battery.
