Abstract

A sixteen-year-old Friesian mare was admitted to the university clinic with the following clinical signs: anorexia, weight loss, fever, bilateral nasal discharge, unilateral facial paralysis and a non-healing corneal lesion. Endoscopic examination of the upper airways showed thickening of the proximal portion of the right stylohyoid bone. Computed tomography imaging showed pneumocephalus due to grade 3 unilateral temporohyoid osteoarthropathy (THO) with fracture of the petrous temporal bone. The horse did not improve following medical treatment. Surgical intervention was declined by the owner and the horse was euthanized due to poor prognosis. Post-mortem examination confirmed the clinical diagnosis. The prevalence of temporal bone fractures is high in horses with severe THO. However, fracture extension into the cranial vault and pneumocephalus has not been described. This is the first reported case of pneumocephalus due to a fracture of the petrous temporal bone in a horse with THO.

一匹 16 岁的弗里斯兰母马因颞侧骨关节病导致气胸。

大学诊所收治了一匹 16 岁的弗里斯兰母马，临床症状如下：厌食、体重减轻、发烧、双侧流鼻涕、单侧面瘫和角膜病变不愈合。内窥镜对上呼吸道的检查显示，患者右侧腕骨近端增厚。计算机断层扫描成像显示，该马因单侧颞骨骨关节病（THO）3级并伴有颞骨石质骨折而导致气胸。马匹在接受药物治疗后病情没有好转。马主拒绝了手术治疗，由于预后不良，该马被实施了安乐术。死后检查证实了临床诊断。在患有严重THO的马匹中，颞骨骨折的发病率很高。然而，骨折延伸到颅顶并引发气胸的情况尚未见报道。这是首例因颞骨隐窝骨折而导致脑积气的 THO 马病例。
