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.
期刊介绍：
European Radiology (ER) continuously updates scientific knowledge in radiology by publication of strong original articles and state-of-the-art reviews written by leading radiologists. A well balanced combination of review articles, original papers, short communications from European radiological congresses and information on society matters makes ER an indispensable source for current information in this field.
This is the Journal of the European Society of Radiology, and the official journal of a number of societies.
From 2004-2008 supplements to European Radiology were published under its companion, European Radiology Supplements, ISSN 1613-3749.
