METHODS: A 28-year-old woman presented to our hospital with the chief complaint of pain in the left parotid region since the past year. Contrast-enhanced magnetic resonance imaging of the parotid gland revealed a 10-mm high-signal area on T2-weighted images extending from the deep lobe of the left parotid gland to the parapharyngeal space, which could not be visualized on ultrasound. She was suspected to have a malignant tumor because of the presence of a parotid tumor with FBS. Therefore, she underwent CT-guided fine-needle aspiration cytology (FNAC) and was diagnosed with adenoid cystic carcinoma. The patient underwent left parotid tumor resection and left cervical dissection, and her pain during feeding improved postoperatively.
CONCLUSIONS: In a patient with parotid tumor extending into the parapharyngeal space with FBS as the initial symptom, CT-guided FNAC was successfully used to diagnose parotid carcinoma. Symptoms of pain, including FBS, should be considered in cases of malignancy. CT-guided FNAC is effective for lesions that cannot be visualized by ultrasound, such as those in the parapharyngeal space.
方法:一名28岁的妇女在过去一年来我院就诊,主诉为左侧腮腺区疼痛。腮腺的对比增强磁共振成像显示,T2加权图像上有一个10毫米的高信号区域,从左腮腺的深叶延伸到咽旁间隙,无法在超声波上看到。由于存在伴有FBS的腮腺肿瘤,她被怀疑患有恶性肿瘤。因此,患者接受了CT引导下细针穿刺细胞学检查(FNAC),并被诊断为腺样囊性癌.患者行左腮腺肿瘤切除术和左颈淋巴结清扫术,她在进食过程中的疼痛在术后得到改善。
结论:在以FBS为首发症状的腮腺肿瘤扩展到咽旁间隙的患者中,CT引导下FNAC已成功诊断腮腺癌。疼痛的症状,包括FBS,在恶性肿瘤的情况下应考虑。CT引导下的FNAC对超声无法可视化的病变有效,比如咽旁空间。
