“…Magnetic resonance imagaing is an alternative method that may provide additional information about equine SCC of the paranasal sinuses. The use of MRI enables visualisation of tumours of the head in early stages of development and enables the differentiation between neoplasms and inflammatory changes, as described by Gerlach and Gerhards (2008). However, in their retrospective analysis of 33 horses with masses in the nasal region, sinuses and adjacent bones, no case of SCC was reported.…”

Summary This case report describes the history, clinical findings, diagnostic imaging (including computed tomography), gross pathology and histopathology of 2 cases of squamous cell carcinoma in the paranasal sinuses. Radiography of the skull is a useful tool to detect a mass in the paranasal sinuses, but the position, extent and character of the lesion can be better visualised with computed tomography.

“…It has been confirmed that magnetic resonance imaging (MRI) can depict soft tissue with high contrast in imaging examinations of the equine nasal cavity ( 13 ). MRI can show the size, extent and invasion of nasal soft tissue lesions clearly, and to some extent, allow for a judgement about the composition of the lesions ( 14 ). In this study, the radiographic, CT and MRI features of ENA were described in detail of six ENA goats, and the diagnostic value of imaging examination for ENA was discussed.…”

The aim of this study was to describe radiography, computed tomography (CT), and magnetic resonance imaging (MRI) findings of enzootic nasal tumors in goats infected with enzootic nasal tumor viruses. Five of six goats with a mean age of 2 years, showed clinical signs of respiratory disease. Head radiographs showed increased density of the unilateral or bilateral nasal cavity in four goats, and a CT scan showed that the space-occupying lesion of the nasal cavity originated from the ethmoid bone and was enhanced homogeneously postcontrast in all goats. The nasal concha was destroyed and the paranasal sinus mucosa was thickened and filled with fluid in some goats. On MRI, the mass exhibited equal or slightly higher signal intensity on T2 weighted images, equal signal intensity on T1 weighted images, a high signal on fluid-attenuated inversion recovery images and heterogeneous enhancement postcontrast. After dissection, histopathological examination of the mass and virus genome detection of the nasal secretions confirmed that the intranasal mass was a low-grade adenocarcinoma and that the goats were infected with enzootic nasal tumor virus type 2. In conclusion, CT and MRI have high diagnostic values for enzootic nasal tumors because they match the postmortem findings and are more accurate than radiography.
