Is sphenoid sinus opacity significant in patients with optic neuritis?
PURPOSE: Optic neuritis secondary to sinus disease is an infrequent but well-documented association. When a patient presents with signs of optic nerve dysfunction and orbital inflammation the significance of widespread sinus disease on radiology is clear and the management is straightforward. We present a group of patients with isolated optic neuritis and radiological evidence of spheno-ethmoiditis and discuss the clinical relevance of this finding. METHODS: We reviewed the notes of 11 patients with optic neuritis who, because of atypical headache, underwent neuroimaging revealing sphenoid sinus opacity. Six patients had endoscopic drainage of the sphenoid sinus; 4 were treated medically. RESULTS: Sinus contents included fungal infection (2), mucopurulent material (5), polyps (1) and necrotic tumour (1). Narrowing of the optic canal due to chronic osteomyelitis was found in 1 patient with irreversible optic atrophy. Visual loss was reversible in 6 patients. Four patients had normal rad
