Plain-English summary
A 13-year-old Maltese dog was brought in because it was having trouble breathing, making a snoring sound when inhaling. A CT scan showed a growth in the dog's skull that was affecting the bones around its nose and eyes. Biopsies confirmed that the growth was a type of tumor called a meningioma, which is usually found in the brain but can also occur in other areas like the sinuses. This case highlights that tumors can appear outside the brain in dogs, and the dog may need further treatment based on the findings.

Abstract
A 13-year-old Maltese dog was presented for inspiratory stertor. A computed tomography evaluation was performed and revealed an osteoproductive lesion primarily centered over the frontal bone with infiltration of the adjacent maxillary and nasal bones, focal intracranial invasion, and an associated broad-based, contrastenhancing, extra-axial lesion along the longitudinal cerebral fissure. Rhinoscopic and incisional biopsies of the paranasal mass were obtained, and a meningioma was diagnosed histologically. Based on the imaging features and histopathology results, an extracranial paranasal sinus meningioma was diagnosed in this dog. To the authors' knowledge, this is the first case report describing the computed tomographic findings associated with a secondary extracranial paranasal sinus meningioma in a dog. Key clinical message: Meningiomas in dogs can be present outside of the brain case and should be considered a differential for tumors of the paranasal sinuses.
