What caused this woman’s wrist to swell?

To start, I ordered an updated MRI to plan for an aggressive surgical excision of the diseased tissue. Unfortunately, the imaging had revealed that the infection spread across the woman’s wrist into all eight carpal bones, all five metacarpal bones, and both forearm bones (radius and ulna). Infection of the bone is called “osteomyelitis,” which is also notoriously difficult to cure, even with typical bacteria.
