膀胱癌多层螺旋CT分期与手术病理对照

目的 分析膀胱癌多层螺旋CT表现及CT分期.资料与方法 总结分析44例经手术、病理证实的膀胱癌的多层螺旋CT表现.结果 44例均为移行上皮细胞癌,膀胱癌的多层螺旋CT表现为膀胱壁弥漫性均匀增厚1例,单发结节状肿块22例,多发菜花状肿块21例,病灶呈轻至中度强化,可向腔内或膀胱壁外生长,累及膀胱周围脂肪层及相邻器官和淋巴结转移;33例为T1和T2期的患者24例基底强化线完整,11例为T3和T4期的患者中只有1例基底强化线完整.与病理分期对照,CT分期的准确率达68.2%.结论 多层螺旋CT薄层增强扫描能够显示膀胱癌的特征,可提高膀胱癌的CT分期准确率.

Staging of Bladder Cancer with Multi-Detector Row Helical Computed Tomography Correlated with Pathology

Objective To evaluate multi-detector row helical computed tomographic(MDCT) findings of the bladder cancer in the staging of the bladder cancer.Materials and Methods MDCT findings in 44 patients with bladder cancers confirmed by pathology were assessed retrospectively.Results Transitional cell carcinomas were found in the bladder in all 44 patients on histopathologic examination.CT showed diffuse thickening of the bladder wall in 1 case,solitary nodule in 22 cases,and multiple papillary masses in 21 cases.After contrast administration,the tumor mildly or moderately enhanced.Perivesical fat and adjacent structures and lymph nodes were involved.Among 33 patients with T1 and T2 bladder cancers,the linear enhancement of the bladder wall was identified in 24 patients.In 11 patients with T3 and T4 bladder cancers,the linear enhancement of the bladder wall was demonstrated in 1 patient.Correlated with the staging of the bladder cancer by pathology,the accuracy of MDCT in the staging of the bladder cancer was 68.2%.Conclusion Thin-slice CT could demonstrate features of the bladder cancer,which might increase the accuracy of MDCT in the staging of the bladder cancer.
