The racemose - or arteriovenous - haemangioma of the retina is a rare developmental anomaly. It can be associated with similar vascular anomalies in other regions of the central nervous system (Wyburn-Mason syndrome).
We report a 24-year-old woman with a chronic headache from our outpatient clinic. Other than a white tortuous strand in the retina of the right eye, which resembled a filarium at first glance, no pathologies were found. Its ends were located at the optic disc forming a sling-shaped lesion extending to the anterior nasal periphery. Partial filling was shown by fluorescence angiography. An MRI of the neurocranium detected no additional vascular abnormalities.
So far our patient has not suffered from any visual complaints and she will be followed up yearly.
We show an unusual presentation of a retinal racemose haemangioma. Diagnosis of this entity should prompt further examinations to exclude any additional haemangiomas with respect to the Wyburn-Mason syndrome.
视网膜蔓状血管瘤，即动静脉性血管瘤，是一种罕见的发育异常。它可能与中枢神经系统其他区域的类似血管异常有关（怀伯恩 - 梅森综合征）。
我们报告一名来自门诊的24岁慢性头痛女性患者。除了右眼视网膜上一条白色迂曲的条索，乍一看类似丝虫外，未发现其他病变。其两端位于视盘，形成一个延伸至鼻前周边的吊带状病变。荧光血管造影显示部分充盈。头颅磁共振成像未检测到其他血管异常。
到目前为止，我们的患者没有任何视觉方面的不适，将每年进行随访。
我们展示了一例视网膜蔓状血管瘤的不寻常表现。对该疾病的诊断应促使进一步检查，以排除与怀伯恩 - 梅森综合征相关的任何其他血管瘤。
