目的：加深对鼻咽癌（ＮＰＣ）ＣＴ表现３种类型的认识。材料与方法：１１８例ＮＰＣ，颈淋巴结转移８９例，有完整的３年追踪资料者６４例，其中远处转移和／或局部复发者２７例。根据ＣＴ表现将１１８例ＮＰＣ分为Ⅰ型（ｎ＝２４），Ⅱ型（ｎ＝６０），Ⅲ型（ｎ＝３４），并将ＣＴ表现３种类型与颈淋巴结转移、远处转移和／或局部复发进行相关性研究。结果：ＣＴ所见Ⅱ型较Ⅰ型更易发生颈淋巴结转移，与Ⅰ型和Ⅱ型比较，Ⅲ型转移之淋巴结多小于３ｃｍ；Ⅰ型放疗后３年转移率、复发率较Ⅱ、Ⅲ型为低，随癌肿向深层蔓延，其局部复发和远处转移率逐渐升高，预后愈来愈差。结论：ＣＴ表现分３型能初步反映ＮＰＣ恶性程度。
Objective: To deepen the understanding of three types of nasopharyngeal carcinoma (NPC) CT manifestations. Materials and Methods: A total of 118 cases of NPC and 89 cases of cervical lymph node metastasis were retrospectively reviewed. 64 patients were followed up for 3 years, including 27 cases of distant metastasis and / or local recurrence. According to the CT findings, 118 NPCs were divided into type Ⅰ (n = 24), type Ⅱ (n = 60) and type Ⅲ (n = 34). CT was performed to differentiate NPC from cervical lymph node metastasis, distant metastasis and / Or local recurrence for correlation studies. Results: Compared with type Ⅰ and type Ⅱ, type Ⅱ lymph node metastasis was more likely to occur in cervical lymph node type Ⅱ than in type Ⅰ lymph node. The number of type Ⅲ lymph node metastasis was less than 3 cm. The type 3 radiotherapy group had a higher recurrence rate than type Ⅱ and Ⅲ Low, with the spread of cancer to the deep, the local recurrence and distant metastasis rate gradually increased, the prognosis worse. Conclusion: The CT manifestations of type 3 can initially reflect the malignancy of NPC.
