CT knee

CT of knee demonstrates lucent lesion with a sclerotic rim located eccentrically in proximal diaphysis of right fibula. No cortical breach or periosteal reaction.

Typical CT appearance of non-ossifying fibroma. It is a benign metaphysical lesion, one of "do not touch" lesions. Initially, it located in the methaphysis but during bone growth, it migrates distally to diaphysis (as in our case).
