Bronchogenic cysts (BCs) are rare and usually asymptomatic malformations detected during imaging examinations. We aimed to investigate the clinical and imaging characteristics of patients with BCs.
We retrospectively evaluated patients who received surgery to remove their BCs from January 2015 to January 2019. Their baseline characteristics, clinical information, and imaging results were reviewed.
Our study included 129 patients, with 57 males and 72 females and a mean age of 42.7 years old. The most common location for BCs was the mediastinum (67 patients, 51.9%). Fewer than half of the patients (53 patients, 41.1%) reported clinical symptoms, with chest pain being the most common (16 patients, 30.2%). Neck BCs were more frequently observed in young patients (P = 0.002) and were more often associated with thyroid cancer (P = 0.007). A computed tomography scan was the most commonly used method to diagnose BCs in the lung and mediastinum, whereas ultrasound was the most commonly used diagnostic method for neck BCs. The characteristic images were well-defined, thin-wall cystic lesions in varying densities. A few lesions showed small, calcified spots along the rim or cavities.
Although most BCs were found in the mediastinum, their locations could vary in different sex and age groups. Particular attention should be paid to young patients with BCs in the neck to rule out thyroid cancer.
支气管源性囊肿（BCs）是一种罕见的疾病，通常在影像学检查中发现，无明显症状。本研究旨在探讨 BCs 患者的临床和影像学特征。
我们回顾性分析了 2015 年 1 月至 2019 年 1 月期间因 BCs 接受手术切除的患者。分析了患者的基线特征、临床信息和影像学结果。
本研究共纳入 129 例患者，其中男 57 例，女 72 例，平均年龄 42.7 岁。BCs 最常见的部位是纵隔（67 例，51.9%）。不到一半的患者（53 例，41.1%）有临床症状，最常见的症状是胸痛（16 例，30.2%）。颈部 BCs 更常见于年轻患者（P = 0.002），且更常与甲状腺癌相关（P = 0.007）。胸部和纵隔的 BCs 多通过 CT 扫描诊断，而颈部的 BCs 多通过超声诊断。典型的影像学表现为不同密度的边界清楚、薄壁囊性病变，少数病变沿边缘或腔隙可见小的钙化点。
尽管大多数 BCs 位于纵隔，但在不同性别和年龄组中的位置可能不同。对于颈部的 BCs 患者，尤其是年轻患者，应特别注意排除甲状腺癌。
