FAMILIAL OSTEOMA OF THE CRANIAL VAULT

A case of solitary osteoma of the parietal skull is described in a mot her and her 12-year-old son. There were no other craniofacial or dysmo rphic features and there was no history of previous cranial trauma or inflammatory process and no radiographic evidence of other skeletal le sions in both patients. Family history was otherwise unremarkable. Gar dner syndrome was ruled out by excluding other associated clinical abn ormalities and by family history. The clinical and radiological featur es of the patients' osteomas were different from those of Albright her editary osteodystrophy, fibrodysplasia ossificans progressiva, progres sive osseous heteroplasia and familial ectopic ossification. To the au thor's knowledge this is the first case of the familial presentation o f osteomas.
