Abstract

Optic nerve sheath meningocele is a rare dilatation of the perioptic cerebrospinal fluid space. A 16-year-old patient presented with painless right proptosis. CT showed a well-defined hypodense lesion in the right intraconal orbit with displacement of the extraocular muscles and no bone erosion. MRI showed a 19 × 23 × 21 mm lesion closely related to the optic nerve, with cerebrospinal fluid signal characteristics, no appreciable enhancement and anterior displacement of the globe. The imaging findings were consistent with an optic nerve sheath meningocele.
