CT在脾脏占位性病变诊断及鉴别诊断中的价值

目的:探讨CT在脾脏占位性病变鉴别诊断中的价值.方法:回顾性分析25例经手术病理证实的脾脏占位性病变的CT及病理学资料,分析脾脏占位性病变的CT特征.结果:良性占位性病变中90.9%脾脏为正常至轻度肿大,而恶性57.1%为重度脾脏肿大.良性占位性病变多为单发病灶,边界清晰,钙化多见,呈蛋壳样钙化,淋巴结少见肿大;恶性病变常为多发病灶,边界欠清,钙化少见,呈砂粒样或结节样,淋巴结肿大及腹水多见.结论:脾脏占位性病变CT表现具有一定的特征性,结合临床病史多可正确诊断.

Value of CT in the Differential Diagnosis of Splenic Neoplasms

Objective:To assess the value of computed tomography (CT) in the differential diagnosis of splenic neoplasms.Methods:The CT findings of 25 cases with surgery and pathology proved splenic neoplasms (11 benign and 14 malignant) were retrospectively studied.The CT characteristics and the pathologic findings were correlated.Results:Among the benign lesions,no splenomegaly was assessed in 10 cases (90.9%),yet 8 cases (57.1%) with malignancy showed splenomegaly.Well-defined solitary lesion,intra-tumoral eggshell-like calcifications,with no lymphadenopathy were showed in benign masses.However,multiple ill-defined lesions,intra-tumoral granular or nodular calcification and enlargement of lymph nodes were found in malignant lesions.Conclusion:There were certain CT findings which were helpful in the diagnosis of space occupying splenic lesions.Accurate diagnosis could be obtained mostly,when the CT findings were correlated with clinical history.
