摘要
目的探讨儿童眼眶肿瘤性病变的临床特点及影像学表现。方法对2010年1月到2012年9月间收治的44例儿童眼眶肿瘤性病变的临床资料，将其临床表现、影像检查结果进行回顾性分析。结果44例眼眶肿瘤性病变中良性肿瘤40例，包括血管源性肿瘤21例，囊肿9例，组织细胞病6例，骨性肿瘤4例；恶性肿瘤4例，包括肌源性肿瘤3例，继发性肿瘤1例。良性肿瘤CT多表现为边界清晰，内密度均或不均，可伴骨质压迫吸收，MRI表现TIWI为中低或等信号，T2WI信号明显加强，呈中高或高信号，CDFI表现除外血管源性肿瘤，均未见明显血流信号。恶性肿瘤CT表现边界不清，眼球受压变形，骨质多发生侵蚀性变化，MRI表现Tiwi为中低信号，T2WI为中高信号，强化后明显加强，CDFI可见强弱不等的红蓝血流。结论儿童眼眶肿瘤性病变以良性居多，良性肿瘤中又以血管源性肿瘤最多见，恶性肿瘤最多见横纹肌肉瘤，其临床表现及影像特点对肿瘤诊断、治疗方法的选择有重要临床意义。
Objective To investigate clinical and imaging features in children orbital tumors. Methods Collected 44 children orbital tumors from January 2010 to September 2012, the types, clini- cal manifestation and imaging results were statistical analyzed retrospectively. Results Among 44 cases of tumors, 40 cases were benign tumors which included 21 vasculogenic tumors, 9 cystic tu- mors, 6 histiocytosis and 4 bonic tumors; 4 cases were malignant tumors which included 3 myogen- ic tumors and 1 secondary tumor. Clear boundary, even or uneven density with bone absorption in CT imaging of benign tumors, low signal in T1WI and high signal in T2WI were seen in MR/ im- aging of benign tumors, excluded vasculogenic tumors, no signal of blood flow were found. Howev- er, the boundary were not clear, sometimes combined with destruction of bone and deformation of the eye in CT imaging of malignant tumors, low signal in T1W1 and high signal in T2WI were seen in MR/ imaging of benign tumors, blood signal could be seen. Conclusions The majority of children orbital tumors are benign, the vasculogenic tumors are the most common of benign tumors, rhabdomyosarcoma is the most common tumor of malignant tumors, the clinical and imaging fea- tures have significant value in the diagnosis and treatment.
