摘要:肠道套细胞淋巴瘤合并肠套叠在国内外较为罕见,其临床表现缺乏特异性,CT和肠镜检查有助于诊断,需要与结直肠癌、克罗恩病及淋巴瘤的其他病理亚型相鉴别,确诊仍需依靠病理学检查。本文报道1例成人肠道套细胞淋巴瘤合并回盲型肠套叠病例,旨在提高临床及影像科医生对该病的认识。

ABSTRACT:Intestinal mantle cell lymphoma complicated with intussusception is rare in clinical practice,lacking specific clinical manifestations.CT and colonoscopy are helpful for the diagnosis of this disease,which need to be distinguished from colorectal cancer,Crohns disease,and other pathological subtypes of lymphoma.The diagnosis still needs to be confirmed by pathological examination.This paper reports a case of intestinal mantle cell lymphoma complicated with ileocecal intussusception in an adult,aiming to improve the clinical and imaging doctors understanding of this disease.

套细胞淋巴瘤是起源于淋巴滤泡套区的B细胞淋巴瘤,在淋巴瘤亚型中发生率低,占非霍奇金淋巴瘤的3%~10%[1]。世界卫生组织在2022年发布了第5版造血与淋巴组织肿瘤分类[2],为医生提供了更为详尽和准确的肿瘤分类信息。现报道1例经病理证实的成人肠道套细胞淋巴瘤合并回盲型肠套叠病例,旨在提高临床及影像科医生对该病的认识。
1 临床资料
患者男,52岁,2021年1月因“腹痛、腹泻30 d”就诊于重庆市第六人民医院。体格检查未见明显异常。实验室检查示淋巴细胞比例0.19,C反应蛋白48.33 mg/L,血沉31 mm/h,糖类抗原125 53.30 U/mL,粪便隐血阳性(+)。腹盆腔CT平扫显示回肠末端套入盲肠,形成同心圆状靶征,密度均匀,平扫CT值约49 HU,病变段盲肠、升结肠长度约12 cm,肠腔狭窄,增强后动脉期、门静脉期、实质期病灶呈轻度均匀持续强化,周围脂肪间隙较清晰,肝门区、回盲部、肠系膜及腹膜后大血管旁见多发肿大的淋巴结,部分融合,较大者3.3 cm×2.1 cm,轻度均匀强化,包绕血管,脾脏增大(图1)。结肠镜下可见回肠末端、回盲部及升结肠多发大小不等的息肉样肿物,突出于黏膜表面,表面光滑、血管扩张,部分肠腔狭窄(图2)。……
