Evaluation of Computed Tomography, Clinical and Surgical Findings of Two Cats with Paranasal Tumours
Özet
Feline paranasal tumours are relatively rare and require sufficient imaging for both diagnostic success and planning the treatment of cases. Radiography is inferior to computed tomography for diagnostic purposes near sinonasal cavities and tissues surrounding them, it is widely accepted that CT is the best imaging technique for tumours of this area. With the advent of 3D rendering software, it became possible to show borders of a lesion in a different manner. Such images are simpler to assess even to those with little to no experience with conventional CT. The preoperative CT images of two cats with paranasal area tumours were rendered in this study in hopes of providing better orientation to the surgeon. While the soft tissue details of 3D images were not adequate, they were useful in seeing outline of the tumours and determining the extent of bony destruction. The intraoperative findings of both cats confirmed that the 3D CT findings were useful in orientation and determination of bony defects, as the images were instrumental in determining the limits of the skull. However, the rendered images were inadequate to provide detail on soft tissue borders so conventional CT images were relied on to determine deep soft tissue borders in both cases.
