"cortical erosion: This is the most common type of intraosseous migration. It occurs when calcific deposits erode the cortex, allowing them to spread into the bone marrow"
"subcortical calcium migration: this type of migration occurs when the calcific deposits move from the bone cortex to the subcortical bone"
"intramedullary diffusion: occurs when the calcific deposits spread throughout the bone marrow"
Expected headings
"Plain radiographs and CT"
"amorphous subcortical calcification, osteolysis and sclerotic area - second phase of migration"
