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.
肢体骨肉瘤或软组织肉瘤是一组多样的间充质肿瘤，其组织病理学、流行病学及解剖受累范围广泛。这些肿瘤中有许多会生长并累及相邻的主要神经血管束，从而导致保肢与截肢治疗模式的转变。MRI是评估神经血管受累情况的金标准成像方式，主要基于T2加权脂肪抑制（T2 W FS）轴位序列和T1加权（T1 W）轴位序列。肿瘤周围水肿与肿瘤的鉴别成像模式或表现为肢体肉瘤的管理带来了进一步的见解。本文旨在揭示MRI上肢体肉瘤累及神经血管的各种复杂情况，以采取多学科管理方法。
