Abstract
Objectives: To analyze the CT imaging features of extranodal natural killer/T (NK/T)-cell lymphoma, nasal type (ENKTCL-NT) involving the gastrointestinal tract (GI), and to compare them with those of Crohn's disease (CD) and diffuse large B-cell lymphoma (DLBCL).
Materials and methods: Data were retrospectively collected from 17 patients diagnosed with GI ENKTCL-NT, 68 patients with CD, and 47 patients with DLBCL. The CT findings of ENKTCL-NT were analyzed and compared with those of CD and DLBCL. Data were analyzed using SPSS (version 25.0) and MedCalc (version 18.2.1). p < 0.05 was considered statistically significant.
Results: The 17 patients with ENKTCL-NT included 11 males (64.7%) and 6 females (35.3%) (mean age, 46.41 ± 4.12 years). The CT features of ENKTCL-NT included: circumferential symmetric thickening (100%), moderate thickening (70.6%), skip lesions (52.9%), contiguous lesion (47.1%), mucosal or layered enhancement (70.6%), moderate mural enhancement (64.7%) with non-enhanced regions (47.1%), absence of lymphadenopathy (76.5%), bowel perforation or fistula (17.6%), and peri-enteric blurred fat space (70.6%). The presence of circumferential symmetric thickening, moderate mural enhancement, and non-enhanced regions were more indicative of ENKTCL-NT than CD (17/17 vs. 17/68, 11/17 vs. 22/68, 8/17 vs. 0/68, p < 0.05). The presence of skip lesions, mucosal or layered enhancement, and absence of peri-enteric lymphadenopathy were more indicative of ENKTCL-NT than DLBCL (9/17 vs. 2/47, 12/17 vs. 1/37, 13/17 vs. 19/47, p < 0.05).
Conclusion: CT imaging features can provide useful information for the early diagnosis of ENKTCL-NT and effectively differentiate it from CD and DLBCL.
Key points: Question Extranodal natural killer/T-cell lymphoma, nasal type (ENKTCL-NT) involving the gastrointestinal tract (GI) is highly malignant but easily misdiagnosed by clinicians and endoscopic examination. Findings CT could provide useful information in the diagnosis of ENKTCL-NT involving GI and in differentiating it from Crohn's disease and diffuse large B-cell lymphoma. Clinical relevance This study will help improve the ability of radiologists to diagnose ENKTCL-NT involving GI, and a more predictive diagnosis will also alert clinicians to perform multiple deep endoscopic biopsies, which will contribute to the early diagnosis and treatment of ENKTCL-NT.
目的:分析结外自然杀伤/T (NK/T)细胞型鼻型淋巴瘤(ENKTCL-NT)累及胃肠道(GI)的CT表现特点,并与克罗恩病(CD)和弥漫性大b细胞淋巴瘤(DLBCL)的CT表现进行比较。材料和方法:回顾性收集17例GI ENKTCL-NT患者、68例CD患者和47例DLBCL患者的资料。分析ENKTCL-NT的CT表现,并与CD、DLBCL进行比较。采用SPSS(25.0版本)和MedCalc(18.2.1版本)对数据进行分析。结果:17例ENKTCL-NT患者中男性11例(64.7%),女性6例(35.3%),平均年龄46.41±4.12岁。ENKTCL-NT的CT表现包括:环周对称增厚(100%)、中度增厚(70.6%)、跳跃性病变(52.9%)、连续性病变(47.1%)、粘膜或层状增强(70.6%)、中度壁增强(64.7%)伴非增强区(47.1%)、无淋巴结病变(76.5%)、肠穿孔或瘘(17.6%)、肠周脂肪间隙模糊(70.6%)。围周对称增厚、中度壁强化、非强化区较CD更能提示ENKTCL-NT (17/17 vs. 17/68, 11/17 vs. 22/68, 8/17 vs. 0/68, p结论:CT影像特征可为ENKTCL-NT的早期诊断提供有用信息,可有效与CD、DLBCL鉴别。结外自然杀伤/鼻型t细胞淋巴瘤(ENKTCL-NT)是一种累及胃肠道的恶性淋巴瘤,但极易被临床医生和内镜检查误诊。结果CT对ENKTCL-NT累及胃肠道的诊断及与克罗恩病、弥漫性大b细胞淋巴瘤的鉴别诊断有重要价值。本研究将有助于提高放射科医生诊断涉及胃肠道的ENKTCL-NT的能力,更具预测性的诊断也将提醒临床医生进行多次深部内镜活检,这将有助于ENKTCL-NT的早期诊断和治疗。
