Abstract

This case series investigates the "Target sign" in contrast-enhanced ultrasound (CEUS) of 11 pathologically confirmed schwannomas, characterized by early central hyperenhancement (mean TTP: 15.7 ± 3.2 s) surpassing peripheral regions (19.1 ± 2.8 s). CEUS demonstrated 100% detection of this sign, outperforming grayscale ultrasound (45%), correlating with histologic Antoni A (cellular) and B (myxoid) areas. Findings suggest CEUS improves diagnostic specificity for schwannomas, offering non-invasive microvascular mapping. Limitations include small sample size and retrospective design.

增强超声对神经鞘瘤的“靶征”。

本病例系列研究了11例病理证实的神经鞘瘤的超声造影（CEUS）“靶征”，其特征是早期中枢高增强（平均TTP: 15.7±3.2 s）超过外周区域（19.1±2.8 s）。超声造影显示该征象的检出率为100%，优于灰度超声（45%），与组织学Antoni A（细胞）和B（粘液）区相关。研究结果提示超声造影可提高神经鞘瘤的诊断特异性，提供无创微血管定位。局限性包括样本量小和回顾性设计。

期刊介绍： The Journal of Ultrasound in Medicine (JUM) is dedicated to the rapid, accurate publication of original articles dealing with all aspects of medical ultrasound, particularly its direct application to patient care but also relevant basic science, advances in instrumentation, and biological effects. The journal is an official publication of the American Institute of Ultrasound in Medicine and publishes articles in a variety of categories, including Original Research papers, Review Articles, Pictorial Essays, Technical Innovations, Case Series, Letters to the Editor, and more, from an international bevy of countries in a continual effort to showcase and promote advances in the ultrasound community. Represented through these efforts are a wide variety of disciplines of ultrasound, including, but not limited to: -Basic Science- Breast Ultrasound- Contrast-Enhanced Ultrasound- Dermatology- Echocardiography- Elastography- Emergency Medicine- Fetal Echocardiography- Gastrointestinal Ultrasound- General and Abdominal Ultrasound- Genitourinary Ultrasound- Gynecologic Ultrasound- Head and Neck Ultrasound- High Frequency Clinical and Preclinical Imaging- Interventional-Intraoperative Ultrasound- Musculoskeletal Ultrasound- Neurosonology- Obstetric Ultrasound- Ophthalmologic Ultrasound- Pediatric Ultrasound- Point-of-Care Ultrasound- Public Policy- Superficial Structures- Therapeutic Ultrasound- Ultrasound Education- Ultrasound in Global Health- Urologic Ultrasound- Vascular Ultrasound
