Plain-English summary
A 6-year-old Wirehair Dachshund was brought in because one of its eyes was bulging out (exophthalmos). The vet suspected a benign tumor around the optic nerve and confirmed it was a meningioma through further testing. During the examination, they also found normal retinal cells in the sample, which helped identify the tumor's location and nature. The dog received treatment for the meningioma, and while the abstract does not specify the outcome, such tumors are often managed with surgery or other therapies.

Abstract
A 6-year-old Wirehair Dachshund had a meningioma around the optic nerve that caused exophthalmos. A benign mesenchymal tumor was suspected based on the cytologic pattern of a fine-needle aspirate, and a meningioma was diagnosed by histopathologic examination. In addition to the meningioma cells, the cytologic smears included groups of cells from apparently 4 layers of normal retina. In particular, uniform rod-shaped structures in the cytologic sample could suggest rod-shaped bacteria, but these structures were identified as cylindrical outer segments of photoreceptor rod cells. Other retinal structures recognized included pigmented epithelial layer cells with their uniquely formed pigment granules, the characteristic bi-lobed, cleaved nuclei from the outer nuclear layer, and nerve tissue likely from the outer plexiform layer of the retina.
