Peripheral neurogenic tumors include neurilemoma, neurinoma, and malignant peripheral nerve sheath tumors. All neurogenic tumors share common imaging features. Although differentiation between them is difficult, neurogenic origin can be suggested from their imaging appearances, including fusiform shape, relation to the nerve, "split-fat" sign, associated muscle atrophy and intrinsic imaging characteristics including "target sign" as well as from lesion location along a typical nerve distribution. Our purpose is to make an overview of imaging findings of each type of peripheral nerve sheath tumor with emphasis on characteristic signs and correlate with histologic features. Morton's neuroma and intraneural ganglion are also included as tumors of nerve origin.
周围神经源性肿瘤包括神经鞘瘤、神经瘤和恶性周围神经鞘膜瘤。所有神经源性肿瘤都具有共同的影像学特征。尽管它们之间难以鉴别，但从其影像学表现可提示神经源性起源，包括梭形形态、与神经的关系、“脂肪劈开”征、相关肌肉萎缩以及包括“靶征”在内的内在影像学特征，以及病变沿典型神经分布的位置。我们的目的是概述每种周围神经鞘膜瘤的影像学表现，重点关注特征性征象，并与组织学特征相关联。莫顿神经瘤和神经内神经节也作为神经源性肿瘤纳入其中。
