Four histological subtypes are described in cats and dogs: mesenchymal nasal hamartoma (MNH), epithelial hamartoma, mixed tissue (chondro\u2013osseous and respiratory epithelial adenomatoid hamartoma\/COREAH), and nasal vascular hamartoma. This descriptive, retrospective study aims to describe the computed tomographic (CT) features of feline NHs. Fourteen cats were included (six MNH, six COREAH, one epithelial, and one vascular). Twelve MNH and COREAH were soft\u2010tissue and mineral\u2010attenuating locally invasive nasal masses with expansile behavior (nine unilateral and three bilateral). The nasal turbinate architecture was replaced by exuberant\/disorganized mineral densities arranged in a \u201ccerebroid pattern\u201d in all cases. Contrast enhancement was moderate in 75% of cats. Commonly, the mass extended into the rostral nasopharynx, contralateral choana\/nasal cavity, and nostrils, more rarely into the orbital cavity and\/or facial soft tissue. Focal osteolysis\/atrophy of the paranasal bones was common (10\/12 cases). The epithelial and vascular hamartomas were soft tissue\u2010attenuating unilateral masses without mineral components. Contrast enhancement was marked in the vascular hamartoma. NHs are relatively rare, tumor\u2010like growths in cats that mainly contain mesenchymal elements. Common CT features include expansile nasal lesions that are locally invasive, characterized by a mineral \u201ccerebroid pattern.\u201d Despite the low incidence, it is crucial to be aware of their presence and include them in the differential diagnosis of feline nasal masses.<\/jats:p>","DOI":"10.1111\/vru.70185","type":"journal-article","created":{"date-parts":[[2026,7,11]],"date-time":"2026-07-11T05:12:23Z","timestamp":1783746743000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["CT Findings of Feline Nasal Hamartomas Mimicking Malignant Growth"],"prefix":"10.1111","volume":"67","author":[{"given":"Pamela Di","family":"Donato","sequence":"first","affiliation":[{"name":"AniCura Ospedale Veterinario I Portoni Rossi  Bologna Italy"},{"name":"Antech Imaging Services  Irvine California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2694-905X","authenticated-orcid":false,"given":"Barbara","family":"Brunetti","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences University of Bologna  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Davide","family":"De Lorenzi","sequence":"additional","affiliation":[{"name":"AniCura Ospedale Veterinario I Portoni Rossi  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angela Vittoria","family":"De Magistris","sequence":"additional","affiliation":[{"name":"AniCura Ospedale Veterinario I Portoni Rossi  Bologna Italy"},{"name":"Antech Imaging Services  Irvine California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manuela","family":"Baldinetti","sequence":"additional","affiliation":[{"name":"AniCura Ospedale Veterinario I Portoni Rossi  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6402-930X","authenticated-orcid":false,"given":"Federica","family":"Rossi","sequence":"additional","affiliation":[{"name":"AniCura Clinica Veterinaria dell'Orologio  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara","family":"Bacci","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medical Sciences University of Bologna  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisa","family":"Zambon","sequence":"additional","affiliation":[{"name":"AniCura Ospedale Veterinario I Portoni Rossi  Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Swan","family":"Specchi","sequence":"additional","affiliation":[{"name":"AniCura Ospedale Veterinario I Portoni Rossi  Bologna Italy"},{"name":"Antech Imaging Services  Irvine California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,10]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfms.2010.07.009"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.21521\/mw.5683"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-014-0533-9"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcpa.2017.10.086"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.1997.tb02992.x"},{"key":"e_1_2_9_7_1","first-page":"1","article-title":"Diagnosis of Feline Mesenchymal Nasal Hamartoma by Squash Preparation Cytology","author":"Bottero E.","year":"2018","journal-title":"Veterinary Clinical Pathology"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1177\/1098612X12444998"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/104063870902100630"},{"key":"e_1_2_9_10_1","first-page":"1","article-title":"Nasal Vascular Hamartoma in a Domestic Shorthair Cat","volume":"88","author":"Chamber B.
