【摘要】：目的:探討脾硬化性血管瘤樣結(jié)節(jié)性轉(zhuǎn)化(SANT)的CT診斷價(jià)值。方法:回顧性分析16例經(jīng)手術(shù)病理證實(shí)的SANT的CT平掃及多期增強(qiáng)掃描表現(xiàn)。結(jié)果:(1)CT平掃:16例均表現(xiàn)為脾臟內(nèi)單發(fā)的、類圓形低密度病變,邊界清晰;邊緣無(wú)分葉2例(2/16,占12.5%),淺分葉14例(14/16,占87.5%);5例周圍見(jiàn)假包膜形成(5/16,占31.3%);16例病灶內(nèi)均未見(jiàn)壞死及囊變區(qū)。(2)CT增強(qiáng)掃描:9例動(dòng)脈期、靜脈期邊緣及分隔見(jiàn)輕度強(qiáng)化,病變內(nèi)可見(jiàn)無(wú)強(qiáng)化的低密度區(qū)(9/16,占56.3%),7例見(jiàn)逐漸向心性充填的"輪輻樣"強(qiáng)化影(7/16,占43.8%);10例延遲掃描可見(jiàn)對(duì)比劑逐漸向病變中心填充(10/16,占62.5%);11例病變中心區(qū)域可見(jiàn)不強(qiáng)化的裂隙樣低密度區(qū)(11/16,占68.8%),7例周圍正常血管影可見(jiàn)受壓移位或變形(7/16,占43.8%)。結(jié)論:SANT的CT表現(xiàn)具有一定的特征性,有助于術(shù)前診斷。
[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.
