初级结肠直肠B细胞淋巴瘤是罕见的,并且由于非特异性症状,难以诊断. 这一案例突出了计算机断层扫描 (CT) 和18-F-FDG PET/CT成像的使用,以帮助诊断这种不常见的恶性瘤.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 胃肠病学 胃肠病学
背景情况:
- 初级结肠直肠B细胞淋巴瘤是一种罕见的非霍奇金淋巴瘤,预后不佳.
- 非特定的症状往往导致误诊或延迟诊断,对患者的结果产生负面影响.
- 准确诊断原发性结直肠淋巴瘤是具有挑战性的,因为它的稀有性和传统成像的局限性.
研究的目的:
- 在70岁的男性中报告一例初级B细胞白内障淋巴瘤病例.
- 强调放射性成像方式,特别是CT和18-F-FDG PET/CT在改善结直肠淋巴瘤诊断中的作用.
- 讨论诊断的挑战和活检的必要性,以确认.
主要方法:
- 病例报告:一名70岁的男性被诊断患有阴的原发性B细胞淋巴瘤.
- 对诊断成像技术的审查,包括对比度增强的计算机断层扫描 (CT) 和-18-氧化葡萄糖正子发射断层扫描/计算机断层扫描 (18-F-FDG PET/CT).
主要成果:

Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Digestive Functions of the Large Intestine
As the chyme moves to the colon, it triggers two characteristic sluggish contractions - haustral churning and mass peristalsis. Haustral churning involves the rhythmic contraction and relaxation...
Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
