Magnetic resonance (MR) was conducted for an 8-year-old, intact male Spitz with sneezing, serous discharge and epistaxis from the left nasal cavity. MR imaging showed a nasal cavity-occupied mass of iso-intensity on T1WI , high-intensity on T2WI and markedly enhanced on contrast-enhanced T1WI at parts of rostal to medial ocular angle in the left cavity. After Surgery and intraoperative radiation, the mass was diagnosed intranasal hemangiosarcoma by histopathology. Although the dog showed the finding, which suggested recurrence after the treatment ending, about 30 months later, it maintained good conditions without evidence of metastasis.
对一只8岁未绝育的雄性斯皮茨犬进行了磁共振成像（MR）检查，该犬出现打喷嚏、浆液性分泌物和左鼻腔鼻出血症状。MR成像显示，左鼻腔内有一占位性肿块，在T1加权成像（T1WI）上呈等信号，在T2加权成像（T2WI）上呈高信号，在对比增强T1WI上，左鼻腔内从鼻背至内眼角部分有明显强化。手术及术中放疗后，组织病理学诊断该肿块为鼻内血管肉瘤。尽管这只犬在治疗结束约30个月后出现提示复发的表现，但它仍保持良好状态，无转移迹象。
