Fibrous Dysplasia. 24-year-old female patient with history of diabetes and café au lait spots presenting with long standing anosmia and nasal congestion, and acute left sided visual loss. Coronal CT images showing expansile multifocal osseous lesions with typical internal ground-glass matrix, involving the left cribriform plate (long arrow, a) and crista galli (short arrow, a). This is causing remodelling of the olfactory fossae and is affecting the olfactory pathway. There are similar expansile lesions affecting the anterior clinoid processes (ACP) and the sphenoid sinus (SS) which causes compromise of both optic nerve canals (OC), worse on the left—this accounts for the visual loss in the left eye. The patient was diagnosed with McCune–Albright syndrome (polyostotic fibrous dysplasia with cutaneous and endocrine abnormalities), and surgical decompression of the left optic canal was performed
