An 18-month-old male entire Bloodhound dog was presented with a six-week history of progressive inspiratory dyspnoea, stridor, dysphonia and exercise intolerance. CT scan performed elsewhere had revealed the presence of an unencapsulated nodular mass (3x1x5 cm) dorsal to the larynx and first tracheal rings. Laryngoscopy demonstrated the presence of bilateral laryngeal paralysis and distorted laryngeal architecture suggestive of extraluminal compression. Histopathology results of incisional biopsies from the mass were suggestive of a benign non-neoplastic muscular lesion. Surgery was performed to manage laryngeal paralysis and attempt mass excision. A second histopathology examination confirmed an inflammatory and dysplastic lesion suggestive of a pseudotumour. All clinical signs resolved after surgery and at the 13 months follow-up the dog remains asymptomatic. To the authors' knowledge, this is the first report of a case of laryngeal paralysis caused by a muscle pseudotumour in a young dog.
一只18个月大的未绝育雄性寻血猎犬出现进行性吸气性呼吸困难、喘鸣、声音嘶哑和运动不耐受6周病史。在其他地方进行的CT扫描显示，喉和第一气管环背侧存在一个无包膜的结节状肿块（3×1×5厘米）。喉镜检查显示双侧喉麻痹，喉结构扭曲，提示管腔外受压。肿块切开活检的组织病理学结果提示为良性非肿瘤性肌肉病变。进行手术以治疗喉麻痹并尝试切除肿块。第二次组织病理学检查证实为炎性和发育异常病变，提示为假肿瘤。手术后所有临床症状均消失，在13个月的随访中，该犬仍无症状。据作者所知，这是第一例年轻犬因肌肉假肿瘤导致喉麻痹的病例报告。
