On physical exam, there was a new area of fluctuance on the anterior tibial surface.

A CT scan demonstrated proximal tibia osteomyelitis with an intramedullary abscess, surrounding soft tissue abscesses and septic arthritis of the knee joint (figure 1).

(A) Permeative appearance of the proximal tibial metaphysis and diaphysis with areas of cortical lucency and endosteal scalloping, suspicious for osteomyelitis. (B) Intramedullary fluid collection within the proximal tibial metaphysis/epiphysis, containing hyperattenuating contents with two punctate foci of air measuring approximately 6.7×4.7×16.6 cm, suspicious for an intramedullary abscess. (C) Linear lucencies within the tibial cortex that communicate with multiple rim-enhancing …
