Abstract
Bone or soft tissue sarcoma of the extremity represents a varied group of mesenchymal tumors, with an extensive range of histopathology, epidemiology, and anatomical involvement. Many of these tumors grow to involve the adjacent major neurovascular bundles, leading to a paradigm shift of management between limb salvage and limb amputation. MRI is the gold standard imaging modality for assessing neurovascular involvement, primarily on T2-weighted fat suppressed (T2 W FS) axial and T1-weighted (T1 W) axial sequences. The differential imaging pattern or appearance of peritumoral edema and tumor has led to further insights in managing extremity sarcoma. This article aims to unfurl the various intricacies of neurovascular involvement by extremity sarcoma on MRI for a multidisciplinary management approach.
四肢骨或软组织肉瘤代表了一组不同的间充质肿瘤，具有广泛的组织病理学、流行病学和解剖学意义。许多此类肿瘤生长累及邻近的主要神经血管束，导致治疗模式在保肢和截肢之间发生转变。MRI是评估神经血管受累的金标准成像方式，主要是T2加权脂肪抑制（T2 W FS）轴向和T1加权（T1 W）轴向序列。肿瘤周围水肿和肿瘤的不同影像模式或外观导致了对四肢肉瘤治疗的进一步见解。这篇文章的目的是展开各种复杂的神经血管累及四肢肉瘤的MRI多学科的管理方法。
期刊介绍：
Skeletal Radiology provides a forum for the dissemination of current knowledge and information dealing with disorders of the musculoskeletal system including the spine. While emphasizing the radiological aspects of the many varied skeletal abnormalities, the journal also adopts an interdisciplinary approach, reflecting the membership of the International Skeletal Society. Thus, the anatomical, pathological, physiological, clinical, metabolic and epidemiological aspects of the many entities affecting the skeleton receive appropriate consideration.
This is the Journal of the International Skeletal Society and the Official Journal of the Society of Skeletal Radiology and the Australasian Musculoskelelal Imaging Group.
