脾脏淋巴瘤的CT诊断

目的探讨脾淋巴瘤的CT表现及CT诊断价值,以提高对其诊断能力。方法回顾性分析临床病理证实并经CT检查的淋巴瘤15例,并作文献复习。结果根据病理类型,15例脾淋巴瘤中,巨块型5例,均为脾内单发类圆形边缘不规则巨块性病灶;多发结节型8例,多发类圆形或分叶状、边界清晰的结节性病灶,绝大多数病灶密度均匀,增强后呈轻度均匀或边缘强化,少数结节灶密度不均;弥漫粟粒型2例,CT表现为脾弥漫性肿大,密度减低,其中1例伴有粟粒小结节状低密度灶。9例伴有脾外淋巴瘤。结论脾淋巴瘤的CT表现有一定特征性,腹内脾外病变CT表现有助于诊断。

CT Diagnosis of the Splenic Lymphoma

Objective To evaluate the CT findings and diagnostic value of splenic lymphoma.Methods 15 cases of splenic lymphoma proved by clinical or pathohistological evidence and examined with plain and enhanced CT scans were retrospectively analyzed with literature reviewed.Results Of 15 cases of splenic lymphoma,The CT findings of splenic lymphoma included:5 cases of Solitary pattern displayed as a uniform density,solitary lesion in the liver with mildle uniform enhancement or peripheral enhancement;8 cases of multiple nodular patterndemonstrated multiple,round-like or lobular lesions with uniform density(in most lesions) with clear margin,and with mildle uniformenhancement or peripheral enhancement after contrast medium administration;2 cases of diffuse pattern showed diffuse enlargement of thespleen with hypodensity or miliary low-density foci.Of 15 cases of hepatic lymphoma,the lesion extended out of spleen in 9 cases.Conclusion The CT findings of splenic lymphoma are of certain characteristics,the presence of abdominal lymphoma is also helpful tosuggest the diagnosis.
