Fig. 4From: Reconstruction using a frozen autograft for a skull and humeral lesion of synchronous multicentric osteosarcoma after undergoing successful neoadjuvant chemotherapy: a case report and review of the literatureSystemic bone scan and MRI findings after five courses of neoadjuvant chemotherapy. a The uptake of all lesions on the bone scan was diminished. b Occipital bone lesion. c Right proximal humeral lesion. d Left distal femoral lesion. e The left occipital lesion had slightly shrunk in size on axial enhanced MRI (a white arrow shows the intracortical lesion.). f The enhancement was drastically decreased on coronal MRI of the right proximal humeral lesion. g The size and enhancement was decreased on coronal MRI of the distal femurBack to article page
