睾丸结核的CT诊断

CT Diagnosis of Testicular Tuberculosis

目的:探讨睾丸结核的CT诊断。材料和方法:回顾性分析经手术病理证实或经抗结核治疗治愈而确诊的15例睾丸结核的CT表现。结果:15例平扫睾丸不同程度增大,实质与包膜分界不清,阴囊隔与病侧睾丸融合,睾丸实质密度不均;12例可见多发结节状或斑点状低等混杂密度影,边界尚清或不清;2例可见斑点状钙化灶;1例为结核性睾丸脓肿。增强扫描睾丸呈不均匀强化,低密度灶和钙化不强化,3例呈环状强化,2例呈多环状强化。14例伴有其他脏器结核。结论:睾丸肿大,实质内多发结节状或斑点状低密度灶,增强后不强化或环状强化,睾丸实质与包膜分界不清,阴囊隔与病侧睾丸融合,睾丸内斑点状钙化灶是睾丸结核的CT表现特征。

Purpase To investigate the Computed Tomography （CT） features of testicular tuberculos. Materials and Methods 15 cases with pathologically-proved or therapeutically-proved testicular tuberculosis were collected,and CT findings were ret rospectively analyzed. Results On plain CT images 15 cases showed testicular enlargement to different extents, unclear interface between the capsule and the testicular parenchyma,confluenee of scrotal septa and abnormal testicle and heterogenous density of testicular parenchyma; 12 cases demonstated multiple nodular or spotty iso- and hypodensity. Calcifications were observed in 2 cases; Testicular abscess was seen in 1 case. On contrast-enhanced images,heterogeneous enhancement was observed accom panyed by no enhancement of isodensity and calcification. Ring-like enhancement was observed in 3 cases and polycyclic enhancement in 2 cases. In 14 cases tuberculosis occurred in other organs meanwhile. Conclusion certain CT imaging charactersistics,which will Testicular tuberculosis demonstrated facilitate the diagnosis.
