The authors report spectral-domain optical coherence tomography (SD-OCT) findings in a patient with decalcifying choroidal osteoma accompanied by a choroidal neovascular membrane and serous retinal detachment. A 13-year-old girl was found to have a choroidal osteoma in the left eye. The clinical diagnosis was confirmed by B-scan ultrasonography, computed tomography, and fluorescein and indocyanine green angiography. The SD-OCT findings over the decalcified portion included serous retinal detachment, photoreceptor outer segment disorganization, retinal pigment epithelial atrophy, deformed Bruch's membrane, and choroidal neovascular membrane. In contrast, the retinal structures over the calcified portion appeared to be preserved. SD-OCT showed loss of a vascular appearance and increased thickness in the affected choroid, especially in the decalcified portion. Choroidal thickening may be associated not only with choroidal osteomas, but also with tumor decalcification. These unique features on SD-OCT may be important in understanding poor visual prognosis when decalcification involves the fovea.
作者报告了一名患有脱钙脉络膜骨瘤并伴有脉络膜新生血管膜和浆液性视网膜脱离患者的频域光学相干断层扫描（SD-OCT）检查结果。一名13岁女孩被发现左眼患有脉络膜骨瘤。通过B超超声检查、计算机断层扫描以及荧光素和吲哚菁绿血管造影确诊了临床诊断。脱钙部分的SD-OCT检查结果包括浆液性视网膜脱离、光感受器外段紊乱、视网膜色素上皮萎缩、变形的布鲁赫膜以及脉络膜新生血管膜。相比之下，钙化部分的视网膜结构似乎得以保留。SD-OCT显示病变脉络膜血管外观消失且厚度增加，尤其是在脱钙部分。脉络膜增厚不仅可能与脉络膜骨瘤有关，还可能与肿瘤脱钙有关。当脱钙累及黄斑时，SD-OCT上的这些独特特征对于理解不良的视觉预后可能很重要。
