There is a diffuse mottled and permeative process involving most of the tibial shaft extending to the plafond. Diffuse periosteal reaction along cortex of the tibial shaft.
A more focal 5.5 cm long midshaft lesion expanding the medullary cavity and scalloping endosteum is suspected. There is a bony exostosis in the dorsal proximal tibial shaft.
Cortical disruption at anterior aspect of tibial plafond compatible with minimally displaced pathological fracture. Adjacent soft tissue stranding.
