目的分析几种少见脾病变的ＣＴ表现，提高脾脏疾病的诊断水平。方法采用ＣＴ（ＰＩＣＫＥＲ１２００ＥＸ型ＣＴ），对６例脾梗塞、５例脾转移瘤、１例脾原发恶性淋巴瘤进行平扫和增强，均经手术病理和治疗随访观察证实。结果脾梗塞呈三角形或不规则形低密度区，病变无强化；脾转移瘤为囊状低密度肿块，单发或多发，病灶呈小结节状或环形强化；脾原发恶性淋巴瘤，呈局灶性低密度区和不均匀强化。结论上述几种脾病变均有一定的ＣＴ征象，结合临床可做出正确诊断。
Objective To analyze the CT findings of several rare splenic diseases and to improve the diagnosis of spleen diseases. Methods Six cases of splenic infarction, five cases of splenic metastasis and one case of splenic primary malignant lymphoma were scanned and enhanced by CT (PICKER1200EX type CT). All cases were confirmed by pathology and follow-up. Results The splenic infarction was triangular or irregular low-density area with no enhancement of lesions. Splenic metastasis was cystic low-density mass with single or multiple lesions with small nodules or annular enhancement. The splenic primary malignant lymphoma was Focal low-density area and uneven enhancement. Conclusions The above splenic lesions have certain CT signs, and can be correctly diagnosed in combination with clinical practice.
