Meningiomas are tumors that arise from the thin membranous layer surrounding the central nervous system called the meninges. Specifically, primary orbital optic nerve meningiomas arise from the cap cells of the arachnoid surrounding the intra-orbital portion of the optic nerve.
Clinical and pathologic features of primary orbital meningiomas in the dog were reviewed. Twenty-two meningiomas, confined to the orbit, were identified from the Comparative Ophthalmic Pathology Laboratory of Wisconsin from 1981 to 1997. The dogs ranged in age from 3 to 17 years (mean = 9.2 years). …
18 lis 2024 · Canine meningiomas typically occur as solitary, well-demarcated tumors that grow by compressive expansion with infiltration into the underlying parenchyma.

Orbital disease is common in dogs and cats but is frequently misdiagnosed and subsequently may be treated inappropriately. A general review of normal orbital anatomy is necessary to understand disease processes affecting the orbit. The bony orbit in dogs and cats is classified as incomplete or open because it is encompassed incompletely by bone.
