梨状窝癌的超声表现
The ultrasonic characteristics of pyriform sinus carcinoma
目的 探讨超声在梨状窝癌诊断中的应用价值,为临床诊断提供参考依据。 方法 对2019年1月至2024年4月确诊的7例梨状窝癌患者使用高频超声探头(5~12 MHz)进行颈部及喉咽部超声检查,重点观察梨状窝区域的病变特征。记录病变的大小、形态、边界、内部回声、血流信号等超声特征,并与病理结果进行对比分析。 结果 6例临床表现为吞咽时颈部异物感,其中2例合并吞咽困难。5例为肿块型,常规超声上表现为梨状窝内低回声肿块;2例为浸润型,常规超声上表现为梨状隐窝黏膜下层呈厚薄不均低回声带样增厚。左侧梨状窝癌3例,右侧梨状窝癌4例。同侧颈部Ⅲ、Ⅳ区多发淋巴结转移7例,同时Ⅱ区淋巴结转移1例;梨状窝癌同时合并颈段食管癌2例,椎体多发转移1例。 结论 超声检查在梨状窝癌的诊断中具有重要价值,其特征性表现包括不规则形态、低回声包块、其内可见较丰富血流信号以及颈部淋巴结转移。这些特征有助于早期诊断和评估肿瘤的侵袭性,可为临床治疗提供一定参考。
Objective : To investigate the clinical value of ultrasound in the diagnosis of pyriform sinus carcinoma, so as to provide a reference for clinical practice. Methods The ultrasound images of 7 patients with pyriform sinus cancer in our hospital from January 2019 to April 2024, the characteristic manifestations of high-frequency ultrasound images were retrospectively analyzed and summarized. The pathological results,including lesion size, shape, borders, internal echo, and blood flow signals were recorded and compared. Results There were six cases presenting with a foreign body sensation in the neck during swallowing,including two cases associated with dysphagia. Ultrasound revealed five mass-type lesion presenting as hypoechoic masses in pyriform sinus and two infiltrative-type lesion showing thick of the hyperechoic band in the submucosal layers of the pyriform. There were 3 cases of left-sided pyriform sinus cancer and 4 cases of right-sided pyriform sinus cancer. Ipsilateral cervical lymph node metastases in levels Ⅲ and Ⅳ were observed in all 7 cases, with concomitant level Ⅱ lymph node metastasis in 1 case. 2 cases had concurrent cervical esophageal cancer, and 1 case had multiple vertebral metastases. Conclusion Pyriform fossa carcinoma could be diagnosed by high-frequency ultrasound which provided valuable information including irregular shape, hypoechoic masses, visible abundant internal blood flow, and cervical lymph node metastasis. These features aid in early diagnosis and assessment of tumor invasiveness, providing reference for clinical treatment.
