Perineural (Tarlov) cysts are usually incidental findings during magnetic resonance imaging (MRI) performed for low back pain. However, in a tertiary women's hospital, they may present as incidental findings on gynecological ultrasound imaging. Approximately 40,000 pelvic scans are performed annually in our department. Tarlov cysts were identified in three women between August 2007 and September 2008. In two patients (Cases 1 and 3), these cysts were initially misdiagnosed as hydrosalpinges on ultrasound examination, the latter having a differential diagnosis of an ovarian cyst. Two patients (Cases 1 and 2) were symptomatic, although Case 2 had symptoms that could not entirely be accounted for by the location of the cyst. Although asymptomatic, Case 3 underwent laparoscopy with a view to salpingectomy/cystectomy. In these patients, confirmation of Tarlov cysts was subsequently made on either computed tomography (CT) or MRI. All three patients were managed conservatively. Here we describe their clinical presentation, the appearance of the cysts on ultrasound imaging and on CT or MRI, and their eventual outcomes.
神经周围（Tarlov）囊肿通常是在因腰痛进行磁共振成像（MRI）检查时偶然发现的。然而，在一家三级妇女医院，它们可能在妇科超声成像检查中偶然发现。在我们科，每年大约进行 4 万次盆腔扫描。2007 年 8 月至 2008 年 9 月期间，我们共发现了 3 例 Tarlov 囊肿。在 2 例患者（病例 1 和 3）中，这些囊肿最初在超声检查中被误诊为输卵管积水，后者的鉴别诊断为卵巢囊肿。2 例患者（病例 1 和 2）有症状，尽管病例 2 的症状不能完全由囊肿的位置来解释。虽然无症状，但病例 3 仍接受了腹腔镜检查，目的是进行输卵管切除术/囊肿切除术。在这些患者中，随后通过计算机断层扫描（CT）或磁共振成像（MRI）证实了 Tarlov 囊肿的存在。所有 3 例患者均接受保守治疗。在这里，我们描述了她们的临床表现、超声成像以及 CT 或 MRI 上囊肿的表现，以及她们的最终结果。
