Maxillary osteomyelitis secondary to osteopetrosis

A 41-year-old Japanese woman complained of a gradually enlarging swelling of her left cheek for seven months. She was diagnosed with osteopetrosis by standard skeletal radiographs, and her cheek swelling was diagnosed as maxillary osteomyelitis secondary to osteopetrosis. She underwent a left partial maxillectomy, and her post-operative course was stable with no complications. A literature review is also presented.
