Jaffe Lichtenstein Type of Polyostotic Skeletal Fibrous Dysplasia With the Involvement of Cranial Bones.

Fibrous dysplasia (FD), a benign fibro-osseous bone tumor commonly involving the craniofacial region, presents a wide spectrum of radiographic patterns. When FD lesions are suspected, various imaging modalities and histopathologic analyses may be required to reach a firm diagnosis. Here, the authors report the case of a 10-year-old male patient presenting with polyostotic type of FD with follow-up data for the next 9 years. The patient showed involvement of cranial bones and bilateral femurs, with skin pigmentation and no endocrine disease, consistent with the diagnosis of Jaffe Lichtenstein disease. The craniofacial radiographic features obtained with computed tomography and cone-beam computerized tomography are documented in this article.
