Primary lymphoma of the colon is rare and comprises less than 1% of large bowel malignancies. Secondary colonic involvement in patients with advanced lymphoma is not uncommon and is frequently undetected. The radiographic findings of 34 patients with colonic lymphoma were reviewed. Thirteen patients had primary tumors, while the remaining 21 had colonic involvement secondary to systemic disease. The radiologic features were classified as mucosal nodularity, endo-exoenteric mass, intraluminal mass, mural infiltration, and mesenteric invasion. One patient with diffuse mucosal nodularity developed acute colonic dilatation, while two other patients had pneumatosis coli secondary to local tumor depositions. Lymphoma is now a well-described complication of chronic ulcerative colitis, and a further case is described here. Although colonic lymphoma is a relatively rare tumor, the spectrum of radiologic changes reviewed here may enable a more accurate radiologic diagnosis.
原发性结肠淋巴瘤很罕见,占大肠恶性肿瘤的比例不到1%。晚期淋巴瘤患者出现继发性结肠受累并不少见,且常常未被发现。对34例结肠淋巴瘤患者的影像学表现进行了回顾。13例患者有原发性肿瘤,其余21例有继发于全身性疾病的结肠受累。放射学特征分为黏膜结节状、肠内外肿块、腔内肿块、壁层浸润和肠系膜侵犯。1例弥漫性黏膜结节状患者发生急性结肠扩张,另外2例患者因局部肿瘤沉积出现结肠积气。淋巴瘤现在是慢性溃疡性结肠炎一种广为人知的并发症,本文描述了另外1例病例。虽然结肠淋巴瘤是一种相对罕见的肿瘤,但本文回顾的一系列放射学改变可能有助于更准确的放射学诊断。
