Plain-English summary

A 3-year-old Connemara filly was taken to a horse hospital in the UK because she had a runny nose on one side and swelling in her face. Tests showed that there was a soft tissue mass in her right nasal area that was blocking her nasal cavity, along with problems related to one of her teeth. Further examination of the tissue confirmed that the mass was a type of growth called a fibro-inflammatory polyp. The treatment details and outcome were not provided in the abstract.

Abstract

A 3-year-old Connemara X filly was referred to a UK equine hospital for further investigation of unilateral nasal discharge and facial swelling. Diagnostic imaging documented the presence of a heterogenous, soft tissue opacity with areas of focal mineralisation within the right paranasal sinuses, completely obliterating the nasal cavity, in addition to endodontic disease and significant periapical pathology associated with the right permanent fourth premolar (Triadan 108). Subsequent histopathologic examination confirmed the mass as a fibro-inflammatory polyp.
