Neurilemoma is a primary nerve sheath tumour that usually arises from a peripheral nerve. In a series of eight solitary neurilemomas four benign and four malignant tumours are observed. Three neoplasms are of intrathoracic origin, four tumours arise in the retroperitoneal space and one tumour develops in the duodenal wall. Radiographic findings using computed tomography, ultrasonography and arteriography are presented. All neurilemomas show relatively low density in CT compared with other parenchymal tumours. All benign and three of the malignant neurilemomas reveal good contrast enhancement. Arteriography has an important role in defining the tumour's blood supply and establishing the origin of the tumour. Five of six neurilemomas show hypervascularity in arteriography. Ultrasonography shows cystic degeneration in three malignant and in one benign neurilemoma. Pathologic correlation of peripheral neurilemoma is discussed by using a special immunoperoxidase technique.
神经鞘瘤是一种主要起源于周围神经的神经鞘肿瘤。在一组8例孤立性神经鞘瘤中，观察到4例良性肿瘤和4例恶性肿瘤。3例肿瘤起源于胸腔内，4例肿瘤发生于腹膜后间隙，1例肿瘤发生于十二指肠壁。本文展示了使用计算机断层扫描、超声检查和动脉造影的影像学表现。与其他实质肿瘤相比，所有神经鞘瘤在CT上均显示相对低密度。所有良性神经鞘瘤和3例恶性神经鞘瘤均显示良好的对比增强。动脉造影在确定肿瘤的血供和明确肿瘤起源方面具有重要作用。6例神经鞘瘤中有5例在动脉造影中显示血管丰富。超声检查显示3例恶性神经鞘瘤和1例良性神经鞘瘤有囊性变。通过使用特殊的免疫过氧化物酶技术讨论了周围神经鞘瘤的病理相关性。
