Cortical desmoid: Case Report and Literature Review

We describe a cortical desmoid lesion in a 13-year-old male football player. This case is the typical illustration of symptoms and radiological findings founded in cortical desmoid. Cortical desmoid is benign cortical fibro-osseous lesion that most frequently occurs in the medial supracondylar femur. A traumatic pathogenesis of this lesion is the most probable cause due to higher traction forces at the insertion site of gastrocnemius or the aponeurosis of adductor magnus. It’s usually diagnosed in 10-15-year-old male adolescent who present knee pain, tenderness or swelling. It also can be asymptomatic and incidental finding on radiological exam. Radiologic features depend on the shape and the stage of lesion evolution. It is important to make a correct diagnosis to avoid many additional tests and biopsy, thinking it is a malignant bone tumor. Despite no published therapeutic guideline exists in literature, symptomatic treatment can be considered efficient.
