An 8-year-old asymptomatic boy was referred for a pigmented fundus lesion in his left eye that was suspected to be a possible choroidal melanoma. Visual acuity was 20/20 in each eye. Ocular examination in the upright position revealed a pigmented lesion measuring 4 mm in diameter and 3 mm in thickness located inferior to the fovea. Following supine positioning, the mass floated to the superior macular region. UI-trasonography confirmed a cystic vitreous mass. Observation of the benign vitreous cyst was advised. A free-floating pigmented cyst can resemble a pigmented intraocular tumor, particularly if it is immediately preretinal.
一名8岁无症状男孩因左眼眼底色素性病变前来就诊，该病变怀疑可能是脉络膜黑色素瘤。双眼视力均为20/20。直立位眼部检查发现一个色素性病变，直径4毫米，厚度3毫米，位于黄斑中心凹下方。仰卧位后，肿物漂浮至黄斑上区。超声检查证实为玻璃体囊性肿物。建议对良性玻璃体囊肿进行观察。一个自由漂浮的色素性囊肿可能类似于色素性眼内肿瘤，尤其是当其紧邻视网膜前时。
