Scalp arteriovenous malformations (AVMs) and sinus pericranii are two rare vascular lesions of the scalp that are part of the differential diagnosis in patients with scalp masses. The necessity of treatment of sinus pericranii, due to its risk of catastrophic hemorrhage or scalp necrosis, makes its diagnosis imperative. There are several theories on the pathogenesis of sinus pericranii with some of them stressing the importance of altered hemodynamic parameters in the affected area. An 8-year-old girl presented with a five centimeter soft, reducible scalp mass that had been present since birth. Clinical and radiographic evaluation revealed a sinus pericranii in association with a scalp AVM. She underwent resection of the sinus pericranii followed by embolization and planned separate en bloc resection of the AVM. During resection of the scalp AVM at a later date, the sinus pericranii was noted to have recurred. Concurrent treatment of all vascular anomalies associated with a sinus pericranii appears to be the key to its complete eradication.
头皮动静脉畸形（AVM）和头皮静脉窦是两种罕见的头皮血管病变，是头皮肿块患者鉴别诊断的一部分。由于头皮静脉窦有发生灾难性出血或头皮坏死的风险，因此对其进行治疗很有必要，这使得其诊断至关重要。关于头皮静脉窦的发病机制有几种理论，其中一些强调了受影响区域血流动力学参数改变的重要性。一名8岁女孩自出生以来就有一个5厘米大小、质地柔软、可复性的头皮肿块。临床和影像学评估显示为头皮静脉窦合并头皮动静脉畸形。她接受了头皮静脉窦切除术，随后进行了栓塞，并计划另行整块切除动静脉畸形。在后来切除头皮动静脉畸形时，发现头皮静脉窦复发。同时治疗与头皮静脉窦相关的所有血管异常似乎是彻底根除它的关键。
