Computed tomographic characteristics of frontal sinus ossifying fibroma in a dog. Veterinary Radiology and Ultrasound 2023; 64: E60–E63. https://doi.org/10.1111/vru.13285.http://hdl.handle.net/2263/93864A 10-year-old female spayed Kelpie cross was presented to The Austin Vet Specialists for further investigation of a mineralized, lobulated frontal sinus mass that had previously been detected radiographically. Computed tomography (CT) revealed a large, expansile, well-defined, heterogeneously mineral attenuating mass invading both frontal sinuses. The mass was surgically debulked via a frontal sinusotomy approach. Histopathology was consistent with ossifying fibroma. This is the first published report to describe frontal sinus ossifying fibroma in a dog, and the second to describe CT features of ossifying fibroma involving the cranium in a dog.en© 2023 The Authors.
