一例绵羊脐部肉芽肿的诊疗

A case of diagnosis and treatment of umbilical granuloma in sheep

1只6月龄绵羊腹底脐孔部有1个直径为15 cm的肿块,为了明确肿块性质并进行诊治,采用一般临床检查、血常规、血清生化指标和B型超声波检查方法进行鉴别诊断,并根据诊断结果进行治疗。结果表明:临床检查发现肿块按压无明显痛感,界限分明,质地较硬,表皮紧张,部分皮肤出现溃烂和感染,活动性较小,且触诊未探及疝轮和疝孔,肿物附近血管分布密集且充盈,疑似肿瘤;血常规检查结果提示患羊有炎症,且贫血;血清生化指标检查结果提示患羊肝脏损伤;B型超声波检查结果显示,肿块界限清晰,有多处低回声暗区,回声不均,未见明显血流,初步诊断脐部肿块可能为皮下组织肿瘤或肉芽肿。手术切除肿块并进行组织病理学检查,最终确诊为脐部肉芽肿,未见明显恶性征象。患羊术后肌肉注射氨苄西林钠和氟尼辛葡甲胺注射液进行抗菌消炎和解热镇痛,7 d后恢复良好,说明手术切除肉芽肿效果良好。

A 15 cm diameter mass was found in the ventral base of the umbilicus of a 6-month-old sheep. In order to clarify the nature of the mass for the diagnosis and treatment, general clinical examination, routine blood test, serum biochemical indexes and B-mode ultrasonography were used for differential diagnosis, and treatment was carried out according to the diagnostic results. The results showed that the clinical examination revealed a mass with no obvious pain when pressed, clear boundary, hard texture, and tense epidermis. Some of the skin was ulcerated and infected, less active, and the hernia whorl and hernia hole were not explored on palpation. There was dense and congested vascular distribution near the mass, which was suspected to be a tumor. The results of routine blood test suggested that the affected sheep had inflammation and anemia;the results of serum biochemical indexes suggested that the affected sheep had liver damage;the results of B-mode ultrasound examination showed that the mass was well-defined, with multiple hypoechoic dark areas and uneven echogenicity, and no obvious blood flow was seen. The initial diagnosis was that the umbilical mass might be a subcutaneous tissue tumor or granuloma. Surgical excision of the mass and pathological examination finally confirmed the diagnosis of umbilical granuloma with no obvious signs of malignancy. Postoperative intramuscular injection of ampicillin sodium and flunixin glucosamine injection for antibacterial, anti-inflammatory and antipyretic analgesia in the affected sheep, with good recovery after 7 days.The results suggested that surgical excision of the granuloma was effective.
