ABSTRACT

Diagnosis: Fibrous Dysplasia

History: 54 year old woman with headache and syncope

Findings: CT Head without contrast: Expansile ground glass lesion involving the ethmoid bone and crista galli with extension into the sphenoid sinuses with mass effect on the medial right orbit favored to represent fibrous dysplasia. Follow-up CT of the orbits and sinuses: The known fibrous dysplasia is again seen involving the crista galli and ethmoid bone with extension into the sphenoid sinuses. Minimal interval expansion of the fibrous dysplastic lesion of the ethmoid bone and crista galli into the medial right orbit. Bone Scan: Moderately intense tracer activity in the region of the previously described ground-glass, expansile lesion centered on the ethmoid air cells, involving the crista galli and extending into the sphenoid sinuses

Ddx: • Enchondroma and Enchondromatosis • Eosinophilic Granuloma (Skeletal) • Fibrous Cortical Defect and Nonossifying Fibroma • Giant Cell Tumor • Bone Hemangioma • Primary Hyperparathyroidism • Neurofibromatosis Type I • Paget Disease • Metastases

Dxhow: -Characteristic radiographic features (expansile ground glass bone lesion) and Bone Scan (increased tracer uptake corresponding to involved areas noted on CT scan)

Exam: • Unremarkable physical exam • Laboratory studies within normal limits

No MeSH data available.
