An 8-year-old spayed female border collie dog was diagnosed with an invasive pituitary macrotumor. Five months after radiation therapy, the patient developed paraparesis and lumbosacral pain. Necropsy revealed a pituitary carcinoma with cauda equina drop metastasis. In cases of pituitary masses, meningeal dissemination should be considered if neurologic status declines.
一只8岁已绝育的雌性边境牧羊犬被诊断患有侵袭性垂体大肿瘤。放射治疗5个月后,该患者出现双下肢轻瘫和腰骶部疼痛。尸检发现垂体癌伴马尾神经转移。对于垂体肿块患者,如果神经功能状态下降,应考虑脑膜播散。
