Comparison of CT features of 79 cats with intranasal mass lesions

Objectives This retrospective multicentre study compared the CT characteristics of cats diagnosed with intranasal mass lesions to determine if defining imaging features exist between different tumour types and neoplastic non-neoplastic lesions. Methods The medical records two institutions were reviewed for findings consistent an lesion subsequent histopathological examination. For each scan location, growth pattern, margin distinction, contrast enhancement pattern presence intralesional areas mineralisation or necrosis recorded. facial deformity, location type bone changes, extranasal extension regional lymph nodes size, hilus visibility also documented. Results Thirty-five nasal lymphoma, 28 non-lymphomatous neoplasia (carcinoma sarcoma) 16 inflammatory met inclusion criteria. Cats more likely show unilateral changes (odds ratio [OR] 3.9), calcification (OR infinity) within frontal sinus 4.5), while suffering from lymphoma a mixed 4.5) expansile 7.8), lymphadenomegaly 2.4). in mass-like highly variable overlapped neoplasms but significantly associated absence bony cavity boundaries 10.2). Conclusions relevance Findings current support ability aid discrimination presented lesion.
