title: Monostotic fronto-orbital fibrous dysplasia with convulsion--case report.
abstract: A 28-year-old man presented with monostotic fronto-orbital fibrous dysplasia associated with convulsions. Signs of meningeal irritation were observed. Computed tomography (CT) showed right frontal sinusitis, and destruction from the inner to outer table with expansion of the diploic space. T1- and T2-weighted magnetic resonance imaging showed an abnormal low-intensity mass, with heterogeneous gadolinium enhancement. Although the meningitis resolved, signs of infection continued for 2 months due to sinusitis. Treatment of the right frontal sinusitis was undertaken, accompanied by open biopsy. The histological diagnosis was fibrous dysplasia. Once the infection had completely resolved, orbitofrontal reconstruction was undertaken. Cranioplasty was carried out using cranial bone cement. Three-dimensional CT was valuable to show the likely postoperative result.
