abstractsA 33-year-old female presented to the ophthalmology clinic with right periorbital redness and pain for 12 hours. CT revealed right optic nerve thickening and enlargement. Cranial MRI demonstrated abnormalities in the corpus callosum, bilateral hippocampi, thalamus, basal ganglia, temporal-parietal lobes, and the left frontal lobe. Ocular B-scan ultrasound showed elevated optic disc and high echogenic signals in the right vitreous cavity. The patient had a history of surgical resection, radiation therapy, and chemotherapy for a left occipital glioma two years prior, with pathology indicating astrocytoma (World Health Organization Grade Ⅱ). Combining the patient′s history and diagnostic findings, the confirmed diagnosis is bilateral occipital astrocytoma with invasion into the right transverse sinus, bilateral optic pathways involvement related to the left occipital astrocytoma, and seeding of astrocytoma in the right vitreous cavity.
