Abstract：
Carotid space lesions present diagnostic challenges due to their diverse etiology and varied clinical manifestations. This article critically reviews the anatomy of the carotid space and highlights the spectrum of pathologies within this complex region, illustrated by three case studies. The cases were examined with ultrasonography (USG), computed tomography (CT), and magnetic resonance imaging (MRI). Schwannomas appeared heterogeneously hypodense on plain CT and partially hyperdense on contrast-enhanced CT (CECT), with displacement of adjacent vessels. Vagal-origin schwannomas caused the anteromedial displacement of the internal carotid artery. Paragangliomas were typically homogeneously hyperdense on CECT, with lateral displacement of the internal carotid artery when of carotid body origin. The management of carotid space lesions depends on the resectability of the tumors; unresectable tumors are managed with chemotherapy. This overview enhances clinical understanding and diagnostic accuracy, facilitating improved patient outcomes in managing carotid space lesions.
摘要：
颈动脉间隙病变由于其不同的病因和不同的临床表现而提出了诊断挑战。本文批判性地回顾了颈动脉空间的解剖结构，并强调了这个复杂区域内的病理谱，由三个案例研究说明。这些病例进行了超声检查（USG），计算机断层扫描（CT），磁共振成像（MRI）。神经鞘瘤在平扫CT上出现不均匀低密度，在对比增强CT（CECT）上出现部分高密度，邻近船只的位移。迷走神经鞘瘤引起颈内动脉前内侧移位。副神经节瘤通常在CECT上均匀高密度，颈内动脉侧向位移时，颈动脉体起源。颈动脉间隙病变的治疗取决于肿瘤的可切除性；不可切除的肿瘤可通过化疗进行治疗。此概述增强了临床理解和诊断准确性，促进改善患者治疗颈动脉间隙病变的结果。
