| 摘 要： | 目的：探讨脾脏错构瘤（SH）的CT诊断价值。方法：回顾性分析9例经病理证实的SH的CT平扫及三期动态增强表现。结果：本组9例中,8例单发病灶,1例多发病灶。单发病灶CT表现：3例平扫呈等密度,4例呈稍低密度（其中2例边缘伴钙化）,1例呈高密度,病灶呈爆米花样钙化。多期增强扫描表现为动脉期弥漫性不均匀轻度强化或周围斑片状强化（6例）,动脉期明显强化（1例）,延迟后上述病灶均接近或稍高于脾实质密度。1例爆米花样钙化各期均未见强化;本组1例多发病灶者共发现8个病灶,最大径1.2～9.5cm不等,CT显示脾上极1个病灶以囊性为主,边缘弧形钙化。其余病灶为实性结节或肿块,以等低密度为主,边界欠清,增强后呈弥漫性、渐进性强化。结论：SH的CT表现有一定特征,当CT平扫显示脾内等或稍低密度实性肿块,伴或不伴钙化,多期增强扫描动脉期病灶呈弥漫性不均匀轻度强化或周围斑片状强化,随时间延迟呈渐进性强化,延迟期接近或稍高于脾实质密度时有助于SH的诊断。

| Abstract: | Objective:To investigate the CT features of splenic hamartoma(SH) so as to promote the diagnostic accuracy.Methods:CT images of 9 cases of SHs were analyzed retrospectively and were correlated with pathological findings.Results:There were solitary lesion in 8 patients and multiple lesions in 1 patient in the present study.The CT findings of solitary lesion:unenhanced CT images showed isodense in 3 lesions and slightly hypodense in 4 lesions(2 lesions were associated with punctural or plaque calcification).E... |
