Aseptic necrosis of trochlea (Hegemann’s disease) is very rare. The diagnosis was done only by x-ray. At early stage it is sometimes difficult by X-rays alone to distinguish aseptic necrosis from other conditions, like as osteochondritis dissecanse or normal growth ossification center with fragmentation. There is one case report of MRI finding, which was helpful for diagnosis of aseptic necrosis. We report the natural history of aseptic necrosis of trochlea by radiology and confirmed the cure by MRI. We took MRI twice once at the early stage and one after the recovery of aseptic necrosis. Through both radiological and MRI findings, we precisely describe the natural evolution of aseptic necrosis of trochlea
