Demographics:
60 years old, Male
Indication:
Right eye vision loss
Findings
- Possible restricted diffusion in the posterior intraorbital right optic nerve
- Asymmetric small caliber of the left optic nerve with associated T2/FLAIR signal hyperintensity
- Abnormal flow-related signal in the visualized portions of the right internal carotid artery, though there is normal flow-related signal loss in the right MCA and ACA
- No evidence of acute infarct involving the brain, hemorrhage, mass effect, or hydrocephalus
- Moderate mucosal thickening of the left maxillary sinus with mild scattered areas of mucosal thickening involving the right maxillary sinus and bilateral ethmoid air cells
Diagnosis
Internal carotid artery occlusion
Sample Report
Abnormal flow-related signal in the visualized portions of the right internal carotid artery, raising concern for high grade stenosis or occlusion. Recommend head and neck CTA for further evaluation.
Possible restricted diffusion in the posterior intraorbital right optic nerve, concerning for ischemic optic neuropathy. Recommend ophthalmology evaluation.
Asymmetric small caliber of the left optic nerve with associated T2/FLAIR signal hyperintensity, suggestive of sequela of prior optic neuritis.
No evidence of acute intracranial abnormality.
Left maxillary sinusitis.
