儿童眼部良性肿瘤的临床CT诊断

Clinical CT Diagnosis of Pediatric Benign Tumors in Ocular Region

目的:总结分析儿童眼部良性肿瘤的CT表现,提高影像诊断水平。方法:回顾性分析经过手术病理、临床及影像综合诊断证实的儿童眼部良性肿瘤37例,分析其CT影像学改变。其中脉络膜骨瘤4例、脉络膜血管瘤1例;毛细血管瘤6例,海绵状血管瘤13例,淋巴血管瘤4例;神经纤维瘤4例,视神经胶质瘤3例,肌纤维母细胞瘤1例,肌上皮瘤1例。结果:大部分(35/37)儿童眼部良性肿瘤CT诊断较为明确;少数罕见肿瘤(2/37)不具有特有的临床及影像征象而难以术前诊断,如肌纤维母细胞瘤和肌上皮瘤。结论:累及儿童眼部的大部分良性肿瘤通常都有相对明确的影像征象,结合临床资料,CT对定性诊断有重要的应用价值。

Objective：To analyze the CT findings of pediatric benign tumors in the ocular region for the purpose of improving the imaging diagnostic level. Methods：The CT images of thirty-seven cases of pediatric benign tumors in the ocular region were retrospectively analyzed,including 4 cases of choroidal osteoma, 1 choroidal angioma, 6 capillary angioma, 13 cavernous hemangioma,4 lymphangioma; 4 neurofibromatosis; 3 optic glioma, 1 myofibroblastoma and 1 myoepithelioma. Results： Most pediatric benign tumors in the ocular region could be diagnosed pre-opertively according to their CT findings, the relatively accurate pathological diagnosis might be acquired if clinical information was also considered. On the other hand, there were a few rare tumors lack of pathognomonic imaging signs from which to make a distinctive diagnosis, such as the myoepithelioma and myofibroblastoma. Conclusion：CT can provide valuable information for diagnosing pediatric bengin tumors in the ocular region.
