<human>: My wife had an MRI that indicated a left calvarial centrally lytic and peripherally sclerotic lesion possibly representing a benign osteoid osteoma. All research we have done indicates that they usually small, do not grow, and sometimes disappear. Is this also true with ones that are in the skull?
<bot>: Hi, Thank you for posting your query.First, I would like to reassure you that there is no need to worry about your wives MRI findings. They represent a benign tumor of the bone, and would not do any harm to her. In some cases, it may disappear on its own, however, it would persist in most people. In a few cases, it may grow in size. If it grows, it is better to excise (remove) it by surgery. I hope my answer helps. Please get back if you have any follow-up queries or if you require any additional information. Wishing you good health, Chat Doctor. Ly/
