In this pictorial review, we present diverse imaging features of spinal schwannomas with an idea to familiarize spine imagers with the varied spectrum of presentation of these tumors. Different types of spinal schwannomas presented include multiple schwannoma (n = 3), schwannoma with cystic degeneration (n = 3), schwannoma with hemorrhage (n = 2), melanotic schwannoma (n = 1), intraosseous schwannoma (n = 2), schwannoma growing into the foramen transversarium (n = 1), intramedullary schwannoma (n = 1), large or giant schwannoma (n = 1), malignant schwannoma (n = 2), and infarcted schwannoma (n = 1). We present imaging findings in these cases and review their differential diagnosis. Awareness of the uncommon presentations of these seemingly common tumors is important in offering a correct diagnosis.
在本图像综述中，我们展示了脊柱神经鞘瘤的多种影像学特征，旨在使脊柱影像诊断医生熟悉这些肿瘤的多样表现形式。所呈现的不同类型的脊柱神经鞘瘤包括多发神经鞘瘤（n = 3）、伴有囊性变的神经鞘瘤（n = 3）、伴有出血的神经鞘瘤（n = 2）、黑色素性神经鞘瘤（n = 1）、骨内神经鞘瘤（n = 2）、长入横突孔的神经鞘瘤（n = 1）、髓内神经鞘瘤（n = 1）、大型或巨大神经鞘瘤（n = 1）、恶性神经鞘瘤（n = 2）以及梗死性神经鞘瘤（n = 1）。我们展示了这些病例的影像学表现，并对其鉴别诊断进行综述。认识到这些看似常见的肿瘤的不常见表现形式对于做出正确诊断很重要。
