6例儿童脾脏原发性孤立性肿瘤影像学表现

目的探讨儿童脾脏原发性孤立性肿瘤影像学表现。方法回顾性分析2010年1月至2015年8月间经手术、病理证实的6例儿童脾脏原发性孤立性肿瘤的影像学特征,并复习相关文献。结果 6例患儿中,2例为囊性病灶,超声表现为无回声肿物,CT平扫表现为低密度肿物,增强后无强化,病理证实为先天性囊肿;2例超声表现为实性等回声,彩色多普勒超声可探及血流信号,CT增强表现为明显低于周围脾实质的强化,病理证实为脾脏淋巴管瘤;1例超声表现为等回声肿块,血流信号丰富,MRI扫描T1WI等信号、T2WI等信号肿块,增强后稍欠均匀强化,病理证实为脾脏错构瘤;1例超声无法辨别肿块边界,CT增强扫描示向心性充填性强化,病理证实为血管瘤。结论儿童脾脏原发性孤立性肿瘤,临床缺乏特异性,影像学检查可明确肿瘤部位,并有助于鉴别诊断,但最终仍需病理确诊。

Imaging features of 6 children with splenic primary solitary tumor

Objective To explore the imaging features of pediatric splenic primary solitary tumor. Methods The medical imaging appearances of 6 children with splenic primary solitary tumor conifrmed by surgery and pathology from January 2010 to August 2015 were retrospectively studied. The related literatur were reviewed. Results In 6 children, 2 children of cystic lesions, ultrasound showed anechoic mass, CT scan showed low density mass, without change after contrast, pathologically conifrmed as congenital cyst;2 children’s ultrasound showed solid echo, color Doppler ultrasound explored the blood lfow signals, contrast CT showed the lower strength around the splenic parenchyma, pathologically conifrmed as splenic lymphangioma;one child’s unltrasound showed echo mass with rich signals of blood lfow, MRI scans showed T1WI, T2WI and other signals of lumps, with little homogenity after contrast, pathologically conifrmed as splenic hamartoma;one child’s ultrasound cannot distinguish tumor boundaries, contrast CT scan showed concentric filling reinforcement, pathologically confirmed as hemangioma. Conclusion Splenic primary solitary tumor in children is rare. There are no speciifc clinical characteristics. The image ifndings can deifne the locations and help the differential diagnosis. The ifnal diagnosis depends on pathology.
