| ［摘要］ 综述腹部病理性淋巴结的CT检查技术及其CT表现和病理基础。腹部淋巴结病变包括结核、淋巴瘤、转移性肿瘤等。淋巴结结核CT强化表现为淋巴结肿大，呈周边环状强化，其优势解剖分布与感染途径密切相关。淋巴瘤的淋巴结肿大常均匀强化，少数均匀强化合并坏死，当累及邻近血管时表现为“夹心饼征”，优势的累及腹主动脉周围上、下部淋巴结。转移性肿瘤淋巴结增大多表现混杂或不均匀或周边强化，优势解剖分布取决于原发肿瘤的淋巴引流途径。 |

| Abstract: |
| ［Abstract］ This paper reviews CT techniques, CT manifestations and pathologic basis of the abdomen lymphadenopathy. The abdomen lymphadenopathy has tuberculosis, lymphoma and metastasis etc. Tuberculous adenopathy commonly shows lymphadenectasis, peripheral enhancement, frequently involved extent relating to the infection routes of abdomen tuberculous.Lymphomatous adenopathy often shows homogeneous enhancement, a few accompany necrosis, sometimes lymphadenectasis encased vessel as “sandwich”, frequently involved the upper and lower paraaoratic lymph nodes.Metastasis lymphadenectasis mostly shows mixed or inhomogeneous enhancement, and the anatomic distribution relating to the draining course of the lymphatics. |
