Plain-English summary
This report discusses an 8-year-old Thoroughbred mare who had a long-term issue with a runny nose on one side. After examining her and doing some imaging tests, the vets initially thought she had an ethmoidal hematoma, which is a type of growth in the nasal area. However, after surgery to remove the mass, they found a hole in a bone at the top of her nasal cavity that connected to her brain. Further testing revealed that the mass was actually an adenocarcinoma, a type of cancer. The findings suggest that when dealing with large growths in the nasal area, it's important to check for any damage to surrounding bones.
Abstract
This clinical report describes an 8-year-old Thoroughbred mare that was presented for evaluation of a chronic, unilateral nasal discharge. Findings on physical examination, radiology, and video-endoscopy supported a clinical diagnosis of ethmoidal hematoma. After surgical ablation of the mass a defect was detected in the cribriform plate. At necropsy a 1.5 cm aperture was identified in the left cribriform plate allowing direct communication between the fundus of the nasal cavity and the cranium. Histology of the mass identified tissue consistent with an adenocarcinoma. History of profuse epistaxis warrants further investigation to differentiate malignant lesions from the more common benign lesions. During surgical ablation of large, space-occupying masses of the caudodorsal nasal cavity the cribriform plate should be examined for defects or secondary erosive lesions.
