CASE HISTORY
Two young, large-breed female dogs were presented with an acute onset of sneezing and nasal discharge. One patient had concurrent epistaxis and facial deformity.
CLINICAL FINDINGS
Decreased airflow was noted through the left nostril in Case 1, while Case 2 showed facial deformity. Nasal radiographs from Case 1 showed a soft tissue opacity in the left nasal cavity and frontal sinus. Rhinoscopy revealed roughened, erythematous nasal turbinates in both patients, and a mass in the left caudal nasal cavity of Case 1. Cryptococcus spp. were demonstrated histopathologically on a nasal biopsy. Tissue culture and serum antigen titres were positive for Cryptococcus spp.
DIAGNOSIS
Chronic rhinitis secondary to Cryptococcus gattii infection in Case 1, and Cryptococcus neoformans infection in Case 2.
CLINICAL RELEVANCE
These are the first reported cases of Cryptococcus spp. rhinitis in dogs in New Zealand.
病例史
两只年轻的大型雌性犬出现急性打喷嚏和鼻分泌物增多症状。其中一只犬同时伴有鼻出血和面部畸形。
临床检查结果
病例1左侧鼻孔气流减少，病例2存在面部畸形。病例1的鼻X光片显示左侧鼻腔和额窦有软组织密度增高影。鼻镜检查发现两只犬的鼻甲均粗糙、充血，病例1左侧后鼻腔有肿物。鼻腔活检组织病理学检查显示新型隐球菌。组织培养和血清抗原滴度检测新型隐球菌均呈阳性。
诊断
病例1为继发于加氏隐球菌感染的慢性鼻炎，病例2为新型隐球菌感染。
临床意义
这些是新西兰首次报道的犬新型隐球菌鼻炎病例。
