未经授权:探讨阴阳舌征在舌偏患者中的诊断价值。
未经证实:根据CT/MR上存在阴阳舌征象,将107例舌偏曲患者分为阳性组和阴性组。评估阳性组中舌下管(HC)的受累类别,并将其分类为HC扩张和HC侵蚀。分析了HC参与类别与体征存在之间的相关性。
UNASSIGNED:阳性组55例(55/107,51.4%),阴性组52例(52/107,48.6%)。舌下神经(HN)受累主要发生在颅底(61.8%),颅底和颈动脉间隙(10.9%),和颈动脉间隙段(12.7%)。神经性(50.9%),鳞状细胞癌(14.5%),和转移(12.7%)是主要的病因。敏感性,特异性,该标志提示HC周围颅底病变的准确性为72.4%,80.8%,76.6%,分别。在积极的群体中,21例(21/55,38.2%)见HC扩张,21例均为良性。在19例患者中发现了HC侵蚀(19/55,34.5%),其中12例是恶性的。
UNASHSIGNED:阴阳舌征是由单侧舌萎缩和HN通路病变引起的脂肪浸润形成的,尤其是累及颅底段的压迫性或侵入性病变。
UNASSIGNED: To investigate the diagnostic value of the Yin-Yang tongue sign in patients with tongue deviation.
UNASSIGNED: According to the presence of the Yin-Yang tongue sign on CT/MR, 107 patients with tongue deviation were divided into a positive group and a negative group. The involvement categories of the hypoglossal canal (HC) in the positive group were evaluated and classified as HC dilation and HC erosion. The correlations between HC involvement categories and the presence of the sign were analysed.
UNASSIGNED: There were 55 cases (55/107, 51.4%) in the positive group and 52 cases (52/107, 48.6%) in the negative group. Hypoglossal nerve (HN) involvement mainly occurred in the skull base (61.8%), skull base and carotid space (10.9%), and carotid space segment (12.7%). Neurogenic (50.9%), squamous cell carcinoma (14.5%), and metastases (12.7%) were the predominant aetiologies. The sensitivity, specificity, and accuracy of this sign for suggesting skull base lesions around HC were 72.4%, 80.8%, and 76.6%, respectively. In the positive group, HC dilation was seen in 21 patients (21/55, 38.2%) and 21 cases were all benign. HC erosion were noted in 19 patients (19/55, 34.5%), of whom 12 cases were malignant.
UNASSIGNED: The Yin-Yang tongue sign is formed by unilateral tongue atrophy and fat infiltration caused by lesions in the HN pathway, especially compressive or invasive lesions involving the skull base segment.
