title: Unilateral tibia vara in a toddler caused by focal fibrocartilaginous dysplasia.
abstract: Focal fibrocartilaginous dysplasia (FFCD) of the tibia is a rare tumor like lesion probably caused by a failure of differentiation in the pes anserinus area. The children usually present with unilateral tibia vara and conspicuous walking features. The radiographic appearance of FFCD is pathognomic. In most cases this benign condition undergoes spontaneous resolution. Curettage or corrective osteotomy is only indicated when the deformity is persistent or progressive. We report the case of a 14 months old toddler diagnosed with FFCD. The characteristic radiographic and MRI features are presented. Further, we present for the first time the sonographic appearance of FFCD.
