Unusual burns of the lower extremities caused by a closed conducting loop in a patient at MR imaging

An extremely rare occurrence of third-degree burns was induced in the medial calves of a male patient with unusual anatomy (after resection and radiation therapy of a liposarcoma) during conventional magnetic resonance (MR) imaging on a clinical 1.5-T MR system that operated without any external conductor present and within safe limits. A closed conducting loop was inadvertently created, which caused focal increased temperature at the junction of his calves.
