Abstract

A 5-year-old castrated male Domestic Shorthair cat presented for evaluation of chronic history of nasal discharge and nasal stridor. On computed tomography (CT), a destructive ill-defined mass of soft tissue attenuation was occupying the right nasal cavity and extending into the left nasal cavity, nasopharynx, and rostral cranial cavity. Histopathology of the rhinoscopically excised samples consisted with destructive granulomatous rhinitis secondary to Leishmania spp. Chronic granulomatous rhinitis with intracranial and nasopharyneal extension secondary to Leishmania spp. infection should be included as a differential diagnosis for a destructive nasal mass of soft tissue attenuation, especially in endemic regions for leishmaniasis.

Keywords: feline leishmaniasis; granuloma; intranasal mass.
