bone-seeking radionuclides administered to mice lead to skeletal tumours : ( a ) osteosarcomata , which are commonly radio-opaque to a variable degree owing to calcified tumour bone , but which may be osteolytic , ( b ) primitive mesenchymal ( angio- ) sarcomata which are non-osteogenic and osteolytic , ( c ) fibrosarcomata -- which also are osteolytic -- and to local or general lymphomata from irradiation of parental cells in bone marrow , but no special radiological features have been found associated with these last-named tumours .
