Pure arterial malformations (PAMs) are rare vascular lesions often detected incidentally on brain imaging. They are characterised by a mass of arterial loops containing arteries that are tortuous, overlapping and dilated without any associated arteriovenous shunting. The incidence of PAMs have been rising due to the increasing use of non-invasive angiographic imaging for the diagnosis of neurovascular disorders. This article will present the clinical course of two cases of PAM, both of which demonstrated a stable appearance on surveillance imaging despite the lack of surgical or endovascular intervention.
纯动脉性畸形（PAMs）是一种罕见的血管病变，常在脑影像学检查中偶然发现。它们的特征是一团动脉环，其中包含迂曲、重叠和扩张的动脉，但没有任何相关的动静脉分流。由于非侵入性血管造影成像在神经血管疾病诊断中的广泛应用，PAMs 的发病率不断上升。本文将介绍两例 PAM 的临床病程，尽管未进行手术或血管内干预，但这两例病例的监测影像均显示其表现稳定。
