Objective To report a case of giant cell tumor of the distal fibula combined with ipsilateral angiolipoma in the tibia.Methods A male patient ( 15 years old ) complained with the intermittent pain in the right ankle for 2 years which was aggravated in one week. Physical examination: swelling of 6cm to the right lateral superior condyle, normal local temperature, no mass, no local tenderness, no limitations of the ankle function. Tibiofibula X-ray of right side: distal metaphysis of the fibula was destroyed expansively, bone mineral density ( BMD ) was decreased, cortex of the bone was thinner, compartment could be seen in the focus of infection, no periosteal reaction or soft tissues. MRI of the right ankle: abnormal nonuniform signals were showed in cavum medullare of the distal ifbula ( 4.5 cm×2.0 cm, equal T1, short T2 ) with clear border, compartment in the focus of infection, and thinner bone cortex; uniform signals were showed in cavum medullare of the distal tibia ( 3.7 cm×1.7 cm, long oval T1, T2
