Choroidal hemangioma is a rare, benign vascular ocular tumor that presents as either a circumscribed mass or as a diffuse variant. Circumscribed choroidal hemangiomas (CCH) resemble posterior segment lesions such as choroidal melanoma, choroidal metastases, central serous chorioretinopathy, or nonspecific retinal detachment. A circumscribed choroidal hemangioma often appears as a subtle red-orange mass or as a grayish lesion in the posterior choroid. In rare instances, CCH may be associated with subretinal fluid accumulation and retinal detachment.
A 35-year-old Hispanic man presented for a routine eye examination and was observed to have a choroidal lesion in the posterior pole. The lesion is an elevated subretinal mass located superotemporal to the fovea in the right eye. A Humphery visual field 24-2 test found a scotoma corresponding to the location of the lesion. B-scan ultrasound confirmed a fairly dense and large lesion. A-scan showed low to medium internal reflectivity and an acoustically solid lesion. Because the patient was asymptomatic, management through observation was recommended.
Circumscribed choroidal hemangiomas must be adequately differentiated from other vascular tumors. A selective battery of diagnostic tests will facilitate the correct diagnosis. Management of CCH may depend on the character of the lesion and risks of ocular morbidity and vision loss.
脉络膜血管瘤是一种罕见的良性眼部血管肿瘤,可表现为局限性肿块或弥漫性病变。局限性脉络膜血管瘤(CCH)类似于后段病变,如脉络膜黑色素瘤、脉络膜转移瘤、中心性浆液性脉络膜视网膜病变或非特异性视网膜脱离。局限性脉络膜血管瘤常表现为脉络膜后部的细微红橙色肿块或灰色病变。在罕见情况下,CCH可能与视网膜下液积聚和视网膜脱离有关。
一名35岁的西班牙裔男性前来进行常规眼部检查,被发现后极部有脉络膜病变。该病变是一个位于右眼黄斑颞上方的视网膜下隆起肿块。Humphery视野24-2检查发现与病变位置相对应的暗点。B超检查证实有一个相当致密且较大的病变。A超显示内部反射率低至中等,为实质性病变。由于患者无症状,建议采取观察治疗。
局限性脉络膜血管瘤必须与其他血管肿瘤充分鉴别。一系列选择性诊断检查将有助于正确诊断。CCH的治疗可能取决于病变的特征以及眼部发病和视力丧失的风险。
