Perineural arachnoidal gliomatosis: case report Gliomatose aracnoidal perineural: relato de caso
Gliomas are the most common infiltrative neoplasms of the optic nerve and can present as two distinct growth patterns: intraneural glial proliferation and perineural arachnoidal gliomatosis (PAG). It has been suggested that perineural arachnoidal gliomatosis is seen almost exclusively in the setting...

Gliomas are the most common infiltrative neoplasms of the optic nerve and can present as two distinct growth patterns: intraneural glial proliferation and perineural arachnoidal gliomatosis (PAG). It has been suggested that perineural arachnoidal gliomatosis is seen almost exclusively in the setting of neurofibromatosis type 1 (NF1). We describe a child with perineural arachnoidal gliomatosis occurring without neurofibromatosis type 1, supported by both radiographic and histological findings. A 4-year-old female without neurofibromatosis type 1 presented with rapidly progressive right-sided proptosis. Magnetic resonance imaging (MRI) revealed an enhancing fusiform intraconal lesion, which was hypointense on T1 and hyperintense on T2-weighted images: characteristic of perineural arachnoidal gliomatosis, the optic nerve was visualized coursing the tumor.
