title: Monostotic fibrous dysplasia of the left parietal bone--case report.
abstract: A 14-year-old female presented with a hard, painless mass, 5 x 5 cm, in the left parietal region. Skull x-rays showed a radiolucent skull tumor with a sclerotic margin in the parietal region. Computed tomography revealed an intradiploic multilocular mass separated by bony trabeculae. The outer table had thinned and protruded outward. The inner table was also thin and protruded inward slightly. External carotid angiography revealed a faint tumor stain and feeding from the middle meningeal artery. Bone scintigraphy revealed abnormal uptake in the lesion. Total removal of the skull tumor and cranioplasty were performed. The histological diagnosis was fibrous dysplasia. Fibrous dysplasia within the cranial vault is often expressed as painless bulging without neurological symptoms. Surgery is recommended when neurological symptoms and/or cosmetic problems are present. Histological confirmation of the diagnosis is also important.
