Abstract

A 14-month-old Japanese Black heifer presented with unilateral epistaxis and mild swelling of the right face. Radiography revealed a mass with increased radiopacity on the right side of the nasal bridge, extending to the left side. Intranasal endoscopy confirmed a large tumor-like structure protruding into the nasal cavity. Following euthanasia, cranial computed tomography (CT) was performed, revealing a tumor 24.3 × 17.5 × 14.8 cm in size. The tumor occupied the entire right nasal cavity and the frontal and sphenoid sinuses. Histopathological examination revealed that the tumor consisted of well-differentiated trabecular bones and loose connective tissue. Based on these findings, a diagnosis of osteoma was established. This report describes a case of osteoma with an acute course in a Japanese Black heifer.

摘要

一头14个月大的日本黑毛小母牛出现单侧鼻出血和右侧面部轻度肿胀。放射学检查显示鼻梁右侧有一个不透射线增加的肿块，延伸至左侧。鼻内镜检查证实有一个大的肿瘤样结构突入鼻腔。实施安乐死后，进行了头颅计算机断层扫描（CT），发现一个大小为24.3×17.5×14.8 cm的肿瘤。该肿瘤占据了整个右侧鼻腔以及额窦和蝶窦。组织病理学检查显示，肿瘤由分化良好的小梁骨和疏松结缔组织组成。基于这些发现，确诊为骨瘤。本报告描述了一例日本黑毛小母牛急性病程的骨瘤病例。
