【摘要】：目的:探讨脾硬化性血管瘤样结节性转化(SANT)的CT诊断价值。方法:回顾性分析16例经手术病理证实的SANT的CT平扫及多期增强扫描表现。结果:(1)CT平扫:16例均表现为脾脏内单发的、类圆形低密度病变,边界清晰;边缘无分叶2例(2/16,占12.5%),浅分叶14例(14/16,占87.5%);5例周围见假包膜形成(5/16,占31.3%);16例病灶内均未见坏死及囊变区。(2)CT增强扫描:9例动脉期、静脉期边缘及分隔见轻度强化,病变内可见无强化的低密度区(9/16,占56.3%),7例见逐渐向心性充填的"轮辐样"强化影(7/16,占43.8%);10例延迟扫描可见对比剂逐渐向病变中心填充(10/16,占62.5%);11例病变中心区域可见不强化的裂隙样低密度区(11/16,占68.8%),7例周围正常血管影可见受压移位或变形(7/16,占43.8%)。结论:SANT的CT表现具有一定的特征性,有助于术前诊断。
[Abstract]:Objective: to evaluate the value of CT in the diagnosis of sclerosing hemangioma of spleen. Methods: Ct plain and multi-phase enhanced CT findings of 16 cases of SANT proved by operation and pathology were retrospectively analyzed. Results all of the 16 cases showed solitary splenic lesions with round hypodense lesions and clear boundary. There were 2 cases without lobes at the margin, accounting for 12.5%, 14 cases with superficial lobes, 14 cases with 14 / 16, and 5 cases with pseudocapsule formation around 87.5%, accounting for 31.33%. In 16 cases, no necrosis and cystic area were found in all 16 cases. Enhanced CT scan showed slight enhancement in arterial phase in 9 cases, and the margin and septum of vein phase were slightly enhanced. In the lesions, there were 9 / 16 low-density areas without enhancement, accounting for 56.3%, 7 / 16 of the "spoke like" enhancement images with gradual concentric filling, 10 cases with delayed scan, 10 cases with delayed scanning, 10 cases of which were gradually filled with 10 / 16% of contrast agent to the center of the lesion, accounting for 62.5% of the lesion center area was not strong. There were 11 / 16 (68.8%) of the low density areas in the fissure-like areas, and 7 / 16 (43.8%) of the normal vascular shadows around them could be seen to be displaced or deformed. Conclusion the CT findings of Sant are characteristic and helpful for preoperative diagnosis.
