摘要

目的：

分析胰腺腺鳞癌的CT和临床表现，旨在提高对该病的认识。

方法：

回顾性分析复旦大学附属肿瘤医院9例经病理证实的胰腺腺鳞癌患者的临床及动态增强CT资料，重点观察病灶部位、大小、边缘、强化方式、胰周及胰腺外改变等。

结果：

9例患者中，男性6例、女性3例，平均年龄为58.7岁。3例位于胰头、6例位于胰体尾部。肿瘤大小2.0 cm2.0 cm 至10.0 cm6.6 cm不等，平均为3.7 cm4.8 cm。9例肿块均呈浸润性生长，5例侵及胰周组织。2例发生肝、脾转移。8例肿瘤瘤体内发生坏死囊变，仅1例为实性组织。9例肿瘤均未见出血、钙化。肿瘤实性成分在平扫期、动脉期和门静脉期的平均CT值分别为(30.74.7) Hu、(60.214.5) Hu和(71.221.4) Hu。在发生中心坏死的8例肿瘤中，瘤体均呈环形渐进性轻度强化。仅1例实性瘤体呈不均匀中度渐进性强化，未见中心坏死。位于胰头部的2例肿瘤引起胆、胰管轻度扩张，远端胰腺未见明显萎缩。

结论：

胰腺腺鳞癌常发生瘤体内坏死囊变，实性成分在CT中表现为环形渐进性轻度强化，对该病的诊断具有提示意义。

Abstract

Objective:

To analyze the manifestations of pancreatic adenosquamous carcinoma on dynamic contrast-enhanced CT.

Methods:

Nine patients (6 men and 3 women; mean age

58.7 years; range

44-73 years) with pancreatic adenosquamous carcinoma confirmed by pathological examination underwent CT examination. The location

size

margin

contrast enhancement were evaluated.

Results:

The masses were localized in the pancreas (head in 3 cases

body and tail in 6 cases). The tumor size ranged from 2.0 cm2.0 cm to 10.0 cm6.6 cm

with an average size of 3.7 cm4.8 cm. All masses were ill-defined. Five masses i

nvaded the peripancreatic tissues. The solid components CT values were (30.74.7) Hu

(60.214.5) Hu and (71.221.4) Hu on plan scan

arterial phase and portal vein phase. Eight masses with the presence of central necrosis showed heterogeneous and poorly enhanced areas. Only one tumor was moderately enhanced. Two patients with lesions in the head of pancreas had liver and lung metastases.

Conclusion:

CT imaging can provide useful information in the diagnosis of pancreatic adenosquamous carcinoma.
