目的:评价CT扫描在腹内淋巴结结核(ALNTB)诊断中的价值。材料与方法:15例ALNTB 10例经病理证实、5例经临床证实,均行CT平扫和增强扫描,观察其CT表现。结果:ALNTB平扫CT表现为软组织密度的淋巴结肿大或淋巴结钙化。增强扫描以环形强化最常见,多个淋巴结肿大表现为多环状强化,呈花瓣状。少见表现有轻度均匀强化、不均匀轻度强化和无强化(淋巴结钙化病例)。6例合并腹内脏器结核,1例合并结核性腹膜炎。结论:ALNTB CT表现有一定特征性,环形或花瓣状强化和钙化常可提示本病的诊断。
Objective: To evaluate the value of CT scan in the diagnosis of intra-abdominal lymph node tuberculosis (ALNTB). MATERIALS AND METHODS: Fifteen cases of ALNTB were confirmed by pathology. Five cases were clinically confirmed by CT scan and CT scan. The CT findings were observed. Results: ALNTB CT showed soft tissue density of lymph nodes or lymph node calcification. Enhanced scan to strengthen the most common ring, multiple lymph nodes showed multiple ring enhancement, was petal-like. Rarely manifested with mild uniform enhancement, non-uniform mild enhancement and no enhancement (lymph node calcification cases). 6 cases with intra-abdominal organ tuberculosis, 1 case of tuberculous peritonitis. CONCLUSIONS: The performance of ALNTB CT has certain characteristics. The ring or petal-like enhancement and calcification may often indicate the diagnosis of this disease.
