摘要
目的探讨泌尿系统原发类癌的CT与MRI表现,加强对该病的认识。方法搜集4例经手术病理证实的泌尿系统类癌患者的临床、影像及病理资料,3例行CT平扫及增强扫描,1例行MRI平扫及增强扫描。结果右肾类癌3例,膀胱类癌1例,其中3例边界清楚,1例边界欠清。平扫肿块呈实性(1例)或囊实性(3例)密度/信号。增强扫描动脉期(皮质期)3例明显强化,1例轻度强化;静脉及延迟期(实质期及排泄期)3例出现延迟强化,1例为持续性强化。结论泌尿系统类癌临床上罕见,影像上多以实性肿块或囊实性肿块形式存在,内可有钙化,多数实性成分可有强化,但确诊仍靠病理诊断。
Objective To investigate the CT and MRI findings of primary carcinoid tumors in the urinary system and to improve the understanding of this disease. Methods The clinical,imaging and pathological data of 4 cases of urinary carcinoid tumor confirmed by operation and pathology were collected. 3 cases examined with CT plain scan and enhancement,and 1 case examined with MRI plain and enhanced scan. Results 3 cases of right renal carcinoid and 1 case of bladder carcinoid,3 cases had clear boundary,and 1 case was unclear,and the plain mass was solid(1 case) or cystic(3 cases) density/signal. In the enhanced arterial phase(cortical phase),3 cases showed significant enhancement,1 case was mildly intensely enhanced,3 cases in the venous and delayed period(substantial stage and excretion phase) showed delayed enhancement,and 1 case showed persistent enhancement. Conclusion The urinary carcinoid in the kidney is clinically rare. A solid mass or solid-cystic mass was often shown on the images,and calcification in the mass was often displayed. Most of the solid components demonstrated enhancement on post-contrast images,but the diagnosis is ultimately confirmed by pathology.
