[Pseudopapilledema combined with a peripapillary hyper-reflective ovoid mass-like structure: a case report].

A 9-year-old male patient with binocular vision loss for 3 months visited the Department of Ophthalmology of the Jalaid Banner Mongolian Medical General Hospital. The optic disc in both eyes was ruddy and moderately edematous with a blurred margin, and the disc periphery was markedly edematous and elevated. Ocular B-scan ultrasonography and optical coherence tomography (OCT) examinations showed varying degrees of optic disc elevation. Enhanced depth imaging OCT examination revealed a slightly hyper-reflective ovoid mass-like structure with clear boundaries laterally protruding under the retinal nerve fiber layer and above the Bruch's membrane at the site corresponding to the optic disc elevation. The 3D-reconstructed OCT image of the optic disc showed the optic disc elevation and the slightly hyper-reflective ovoid mass-like structure. The clinical diagnosis was pseudopapilledema combined with a peripapillary hyper-reflective ovoid mass-like structure in both eyes. Finally, the patient was followed up in the ophthalmology outpatient department.
