please help! cranial lesion in child

5 Comments / Cases / By

Hi, dear friends,

9yr boy, bony probtuberance in right parietal. What’s the diagnosis? and why the inner band of diploe was sparing? Focus of fibrous dysplasia？
Focal hematopoietic hyperplasia?
Incipient osteoma arising atypically from the diploe?

Thanks!

    I think it is an osteoma involving the tabula externa and therefore the inner part of the diploe is spared.

    I agree 100%

    That’s what i mentioned to Xian

    Ossified hematoma- common lesion at bone sites which get bumped all the time- anterior tibia and skull

    Hello!

    a calcified cephalohematoma should be considered:

    e.g. Fig 36 in :
