原发性胆囊癌的CT诊断及鉴别诊断

目的探讨不同类型胆囊癌的CT表现，以提高对该病的诊断和鉴别诊断水平。方法回顾性分析18例经手术病理证实的胆囊癌的CT资料，均经螺旋CT平扫及增强扫描，分析其CT表现。结果18例胆囊癌按影像学表现分为4种类型：a)胆囊壁增厚型5例，b)腔内型3例，c)肿块型9例，d)胆囊颈型1例。其中5例合并胆囊结石，8例伴肝脏侵犯。结论CT在胆囊癌的诊断与鉴别诊断中具有重要作用。

Diagnosis and differential diagnosis of primary gallbladder carcinoma with CT

Objective To investigate the CT findings of primary gallbladder carcinoma and to elevate its diagnostic level.Methods CT data obtained from 18 patients with surgically and pathologically proven primary gallbladder carcinoma,who underwent conventional plain scans and dynamic enhancement scans were analyzed retrospectively.Results According to CT images,the lesions of primary gallbladder carcinoma in all patients were divided into four patterns,i.e.a)gallbladder wall thickening pattern was found in 5 cases,b)intraluminal pattern in 3,c)mass pattern in 9,and d)gallbladder cervix pattern in1.Among all patients,5 cases associated gallstone while 8 cases presented as direct invasion into liver.Conclusion CT has an important role in the diagnosis and differential diagnosis of primary gallbladder carcinoma.
