摘要
目的：探讨ＣＴ对脾脏占位性病变（ＳＳＯＬ）的诊断及鉴别诊断价值。材料和方法：收集５０例脾脏病变（包括恶性肿瘤２１例，良性肿瘤１１例，结核１１例，脓肿２例，囊肿５例）的ＣＴ资料，分析脾脏大小、病灶数目、密度、边界、强化程度等表现。结果：脾脏恶性肿瘤多表现为单发或多发低密度灶，边界不清，增强后无强化或轻度不均一强化，脾脏肿大显著，常伴淋巴结肿大。良性肿瘤多表现为边界清、密度均匀低密度灶，脾脏不大或轻度增大。血管瘤、错构瘤强化显著；淋巴管瘤强化不明显；脾结核多表现为多发或弥漫性大小不等结节状低密度灶，边缘模糊，增强后病灶无强化，常伴后腹膜、脾门区淋巴结肿大及其他脏器结核等。结论：ＣＴ可较好地显示脾脏大小、病灶密度、边界及ＣＴ强化程度，ＣＴ对大多数脾脏占位性病变可作出正确的定性诊断。
Purpose: To evaluate the value of CT in diagnosis and differential diagnosis of splenic space - occupied le sions(SSOL) .Materials and Methods: The CT findings in 50 cases with various SSOL were analyzed. Results: Solitary or multiple lesions, ill - defined, lower density as compared with spleen tissue in precontrast images , nonenhancement accompanied with uneven enhancement of spleen, swelling of lymph- nodes were found in malignant splenic tumors.Otherwise well defined, lower density lesions with noninvolvement of lymphnodes were seen in benigh splenic tumors,but remarkable enhancement in hemangioma and hamartoma. Splenic tuberculosis usually had multilpe low - density, ill - defined outline and nonenhance- ment foci, had lymphadenopathy in retroperitoneal and splenichilum region, and accompanied with tuberculous lesions of other visceral organs. Conclusion: SSOL could be qualified accurately by CT.
