目的探讨舌癌影像解剖特点,进一步分析MRI征象并评价其诊断价值。方法搜集52例有完整资料的舌癌患者,所有患者术前皆行MRI检查,结合影像解剖特点,分析其原发灶、局部侵犯及颈部淋巴结转移的MRI表现,并与手术病理结果进行对照。结果 52例中鳞状细胞癌45例,腺癌4例,腺样囊腺癌3例。MRI对舌癌原发灶的部位、大小、周围情况及颈部淋巴结转移情况显示较好。其中发生在舌体43例,舌根5例,舌尖4例;12例向周围组织浸润,分别累及咽侧壁、扁桃体、下颌骨、舌骨、口底、舌底;23例转移至颈深淋巴结上中组及下颌下、颏下淋巴结,2例向咽后淋巴结转移。结论舌癌在发病部位、形态、肿瘤信号、周围组织结构的侵犯和颈部淋巴结转移都有一定的解剖学及影像学特征,MRI对于舌癌的鉴别诊断和病变范围的判断有重要价值。
Objective To investigate the anatomic features of tongue cancer and to further analyze MRI signs and evaluate its diagnostic value. Methods Totally 52 tongue cancer patients with complete data were collected. All patients underwent preoperative MRI examination. Combined with the anatomical features of the images, the MRI findings of primary tumor, local invasion and cervical lymph node metastasis were analyzed and compared with those of surgical pathology . Results 52 cases of squamous cell carcinoma in 45 cases, adenocarcinoma in 4 cases, adenoid cystadenocarcinoma in 3 cases. MRI of the tongue of the primary tumor location, size, surrounding conditions and cervical lymph node metastasis showed better. Among them, 43 cases occurred in the tongue, 5 cases in the tongue, 4 cases in the tongue, 12 cases infiltrated into the surrounding tissues, involving the pharyngeal side wall, tonsil, mandible, hyoid bone, mouth and tongue, respectively. On the group and submandibular, submental lymph nodes, 2 cases of lymph node metastasis. Conclusion The tongue cancer has some anatomical and imaging features in the pathogenesis, morphology, tumor signal, surrounding tissue structure and cervical lymph node metastasis. MRI has important value in the differential diagnosis of tongue cancer and the judgment of the scope of the disease.
