Abstract
Neurofibromatosis type 1 (NF-1) leads to cutaneous, neurological, and musculoskeletal manifestations. Congenital pseudarthrosis of the tibia treatment is considered aggressive in achieving bone union. Most of those patients get a short limb at the end of treatment because of pathological bone resection and malalignment. One of the manifestations that can appear in patients is localized hemihypertrophy of the limb. In our case, we present the first time a coexistence of congenital pseudarthrosis of the tibia and hemihypertrophy in the same leg was reported.
