Chronic Rhinitis in Cats

Nasal vascular hamartoma in a Domestic Shorthair cat

“…Excision of vascular hamartomata with wide margins has been recommended in the human literature, although the justification for this remains unclear. Published reports of minimally invasive endoscopic resection or endoscopic‐assisted resection of pedunculated, polypoid masses within the oropharynx with conservative margins have not described recurrence at early follow‐up 5,14,1,18 . The outcome of those reports is consistent with the limited potential of hamartomas to grow past maturity.…”

“…Following demonstration of a mass lesion within the righthand side of the nasal cavity, a tissue sample was required to establish a definitive histological diagnosis to allow prognostication and facilitate treatment decisions. In general, imaging studies should be performed prior to rhinoscopy because haemorrhage, which commonly accompanies rhinoscopy in small animals, introduces artefacts that may confound the images obtained 1 …”

“…In general, imaging studies should be performed prior to rhinoscopy because haemorrhage, which commonly accompanies rhinoscopy in small animals, introduces artefacts that may confound the images obtained. 1 Surgical exploration was elected in preference to repeated minimally invasive biopsy, because of the small size of the patient and the poor diagnostic sensitivity of endoscopic biopsy techniques; the small size of the instruments often results in a superficial tissue sample, which frequently provides a non-specific diagnosis of inflammatory disease. 25 Surgical exploration allows assessment of the feasibility of excisional biopsy, or in the event of its impossibility, collection of a large representative tissue sample for histology.…”

“…The establishment of a definitive diagnosis is frequently facilitated by advanced imaging, which often serves as the basis for additional diagnostic procedures and may facilitate or direct therapy. Potential aetiologies of chronic rhinitis in the cat include viral, bacterial, fungal or parasitic infection, neoplasia, dental and palatine defects, foreign bodies, coagulopathy, lymphoplasmacytic rhinitis, allergic rhinitis, nasopharyngeal polyps and extracranial diseases that result in vomiting 1 . The present case describes the diagnosis and surgical management of a nasal hamartoma in a cat.…”

To the authors knowledge, this condition has not been previously reported in the cat and is an additional differential diagnosis of feline nasopharyngeal disease.…”
