Intraoperative magnetic resonance imaging provides the surgeon with powerfu
l, high-resolution, real-time imaging. Procedures may be performed with min
imal invasion, with the benefit of reduced tissue damage, improved wound he
aling, and a better cosmetic result. The authors present a case of a leukem
ic pediatric patient with a few large, deeply situated, nonpalpable abscess
es that were drained successfully with intraoperative magnetic resonance im
aging guidance. In this case, this new intraoperative imaging method enable
d minimal invasiveness, with fast recovery.
