The calcaneal vascular remnant, first described by Fleming et al. in 2005, is a benign intramedullary lesion of the calcaneus with a vascular origin.
To determine the prevalence and magnetic resonance imaging (MRI) characteristics of incidental calcaneal vascular remnant on routine ankle MRI.
We retrospectively reviewed 457 ankle MRI scans for the presence of calcaneal vascular remnant. MRI was considered positive when a focal cyst-like area was seen on a T2-weighted sequence, and a low signal intensity was identified on a T1-weighted image beneath the calcaneal sulcus. Patients with calcaneal vascular remnants were further evaluated for age, gender, right or left foot location, size, and lesion characteristics.
The prevalence of incidental calcaneal vascular remnant was 21.7% on our consecutive ankle MR examinations. The average lesion size was 5.5 mm. No statistically significant difference was noted in the frequency of lesion detection between gender, age, and side of the lesions ( > 0.05). Multilobulated lesions were detected predominantly in women ( = 0.013) and classic type lesions were detected predominantly in men ( = 0.036).
This report is the first to determine the prevalence and MRI characteristics of calcaneal vascular remnants. Detecting and reporting this lesion on routine MRI is essential to avoid confusion with other pathologic entities.
跟骨血管残迹由 Fleming 等人于 2005 年首次描述，是一种起源于血管的跟骨骨髓内良性病变。
确定常规踝关节 MRI 检查中偶然发现的跟骨血管残迹的发生率和磁共振成像（MRI）特征。
我们回顾性分析了 457 例踝关节 MRI 扫描，以确定是否存在跟骨血管残迹。当 T2 加权序列上出现局灶性囊肿样区域，且跟骨沟下 T1 加权图像上显示低信号强度时，MRI 被认为呈阳性。对存在跟骨血管残迹的患者进一步评估年龄、性别、病变部位（右脚或左脚）、大小和病变特征。
在我们连续的踝关节 MRI 检查中，偶然发现的跟骨血管残迹的发生率为 21.7%。平均病变大小为 5.5mm。性别、年龄和病变侧别之间的病变检出率无统计学差异（>0.05）。多叶病变主要见于女性（=0.013），典型病变主要见于男性（=0.036）。
本报告首次确定了跟骨血管残迹的发生率和 MRI 特征。在常规 MRI 上检测和报告该病变对于避免与其他病理实体混淆至关重要。
