Popcorn calcification refers to amorphous calcifications often with rings and arcs that resemble popped corn kernels. This type of calcification may be seen in many radiological settings including :
- chondroid lesions (e.g. enchondroma, chondrosarcoma)
- fibrous dysplasia
- pulmonary hamartomas
- degenerating fibroadenomas of the breast: see popcorn calcification in the breast
- calcified uterine fibroid
They are also seen in metaphyses and epiphyses of long bones of children with osteogenesis imperfecta. In this case, they represent scalloped lucencies with sclerotic margins .
